    Development of Non- Asbestos Organic Brake Friction Materials
    Research Scholar: Mr. J. Sudhan Raj, RR13ME003
    under the guidance of Dr. T. V. Christy,
    Professor of Department of Mechanical Engineering.

    The most paramount safety aspect of an automobile is its brake system, which must stop the vehicle and also do so reliably under varying conditions. During a cessation, the kinetic energy of a moving conveyance is converted to heat at the sliding interface of the friction pair. Emission of dust from asbestos during braking causes lung diseases. The raised levels of awareness in health hazards due to asbestos led to non-asbestos friction composites automotive brake disc pads, shoes, linings, blocks, clutch facings, etc.

    Fabrication and characterization of Al syntactic foams
    Research Associate: Mr. Jerin Jose
    under the guidance of Dr. T. V. Christy,
    Professor of Department of Mechanical Engineering.
    Syntactic foams are composite materials synthesized by filling a metal, polymer,or ceramic matrix with hollow spheres called micro-balloons or cenospheres.The presence of hollow particles results in lower density, higher specific strength (strength divided by density), lower coefficient of thermal expansion, and, in some cases, radar or sonartransparency. Tailorability is one of the biggest advantages of these materials. The matrix material can be selected from almost any metal, polymer, or ceramic. Micro-balloons are available in a variety of sizes and materials, including glass microspheres, cenospheres, carbon, and polymers.
    Micro and Nano Heat Transfer Laboratory

    Micro and Nano fabrication techniques have revolutionized the cooling industries as the micro and nano structures enhances boiling heat transfer of cooling devices in many folds. Also micro structures used as a wick structures which are critical for the smooth operation of passive heat transfer devices such as heat pipes and thermosyphons. Development of such micro and nanostructure with good capillarity lead to the possibilities of miniaturization by improving the performance. The Micro and nano heat transfer Lab of the Department of Mechanical Engineering is a flat form to develop such micro and nano structures, characterize and test the same by applying in to the cooling devices such as heat pipes. This laboratory consists modern facilities to test various kinds of heat pipes, Anodizing, Electro plating and many others.

    Currently two research scholars, two masters and eight under graduates are working in this laboratory. One DST sponsored research project and various consultancy projects are ongoing and through these activities more than 50 referred research papers are published.

    Miniature loop heat pipes for cooling high heat flux devices
    The miniaturization and rapidly increasing heat loads of the new electronic devices put forward the challenge of efficient cooling in these devices. This is because of the high heat flux produced by ultra large scale of integration of electronic components into these devices. The present electronic components are very compact in size and the area available for heat dissipation in these devices is very less. The high heat fluxes in miniaturized electronic devices produce thermal stresses which reduce the reliability of these devices. Similarly, the life of electronic components also decreases as their operating temperature increases. Nowadays, miniaturization of electronic devices is the trend. The growing trend of miniaturization increases the heat produced which is comparable with the quantity of heat from a nuclear reactor or surface of the sun on a unit volume basis. The road map of the International Electronics Manufacturing Initiative predicts a maximum heat dissipation of 360W from a high performance microprocessor by 2020.
    Use of typical air cooling or liquid cooling is not sufficient to meet the cooling demands of present and future miniaturized electronic devices. Because, the conventional cooling systems have low convective heat transfer coefficients and the thermal conductivity of coolants used in them has low values. It indicates that cooling is still a challenge that needs to be addressed in many electronic applications. So an effective cooling system with advanced heat transfer fluid has to be developed to meet the current cooling requirements. Moreover, the packaging limitations of the small electronic devices make this problem more complicated. An effective cooling method capable of keeping the temperature of the electronic devices within their safe operating limits and satisfying the compact packaging constraints can only solve this problem.
    Miniature loop heat pipes (mLHP) are capable of transferring large amounts of heat to significant distance with no pumping power because they utilize boiling and condensation phenomena. The other advantages of mLHPs include electricity free operation, ability to work with small temperature difference, compact size and reliability. This technology has been developed in the Centre for Research in Material Science and Thermal Management (CRMSTM) available in the Department of Mechanical and Aerospace Engineering of Karunya Institute of technology and Sciences. A novel miniature loop heat pipe is designed and demonstrated for cooling the high-end central processing units, graphic processing units, integrated bipolar transistors, circuit breaker in low voltage switch board etc. using the research fund received from the Department of Science and Technology, Government of India.
    Composites in Combat: Composites for Military Vehicles

    Soldiers globally are committed to their duty of protecting the country and therefore superior technologies are essential to protect them. One such essential technology is in the development of Composite Materials. The increasing use of composites and innovations in fabrication has enabled composite components to satisfy the need for military vehicle components. Armoured vehicles have traditionally used steel armour. However, this gives rise to heavy structures that provide logistical problems in transporting the vehicles to a battle site. This major hindrance has led to a major increase in the development of composite armoured vehicles.
    The advantages of using composites are enabling weight savings, high payload and fuel efficiency, high performance and speed capability. Since military vehicles are constructed with the protection factor in mind, they are bulky, however composites render them lighter. Composites have an infinite fatigue life and good corrosion resistance in challenging environments. Apart from being used in land combat vehicles, composites are also finding applications in air combat vehicles. Constant pressure for greater fuel efficiency is forcing aircraft manufacturers to find ways to incorporate new materials. Forty years ago, aluminium dominated the aircraft industry. As much as 70% of an aircraft was once made of aluminium. Other new materials such as composites and alloys were also used, including titanium, graphite, and fiberglass, but only in very small quantities – 3% to 7%.
    Times have changed. A typical jet built today has, as little as, 20% pure aluminium. Most of the non-critical structural material – panelling and aesthetic interiors – now consist of even lighter-weight carbon fibre reinforced polymers (CFRPs) and honeycomb materials. Meanwhile, for engine parts and critical components, there is a simultaneous push for lower weight and higher temperature resistance for better fuel efficiency, bringing new materials into the aero material mix. Composite materials represent a growing piece of the aircraft material pie. They reduce weight and increase fuel efficiency while being easy to handle, design, shape, and repair. Once only considered for light structural pieces or cabin components, composites’ aerospace application range now reaches into true functional components – wing and fuselage skins, engines, and landing gear. The mix of materials in aero industry will continue to change in coming years with composites increasingly occupying the space of traditional materials. And it’s all done in the name of reducing the cost; improving fuel economy and making air travel a more cost-effective means of transportation. Being said so much about the advancement in materials technology; it becomes essential for someone to work towards developing new composite materials for the future. In this aspect, the Department of Mechanical and Aerospace Engineering of Karunya Institute of Technology and Sciences have gone leaps and bounds to master this technology. The institution also provides consultancy and testing services for Aluminium based Composite Materials through the Centre for Research in Metallurgy.

    Biomass waste to energy for automotive applications
    The world energy production is based mainly on fossil fuels like crude oil, natural gas and coal. Increase in energy demand results in increasing fossil fuels consumption, which in turn contributes significantly to the environmental pollution and climatic changes. Biomass is considered to be one of the important solutions for substituting the fossil fuel resources. It has a unique potential for making a positive environmental impact, i.e., the CO2 emitted in processing the biomass would be absorbed by the fresh biomass.
    Non edible oil from Jatropha (Jatropha curcas) and Karanja (Pongamia pinnata) Plants are identified as major source for biodiesel production in India (Planning Commission, Government of India, 2003).The Pongamia and Jatropha de-oiled cakes, solid residues that are usually discarded after extraction of oil from the seeds, contains lignin and cellulose in varying ratios. Moreover, due to increasing demand of biodiesel, the quantity of de-oiled cakes has increased tremendously and about 2 tonnes of oil cake is discarded as a waste for every tonne of biodiesel produced. One of the major problems arising in the coming years is disposal of cake after expelling oil from seed. Usage of deoiled cakes as biomass resources rather than disposing it as waste is considered to be the best strategy to produce energy and solve the environmental problems.
    Flash pyrolysis process has been developed in the centre for research in renewable energy (CRRE) under the Department of Mechanical and Aerospace Engineering of Karunya Institute of Technology and Sciences to produce liquid fuels from Jatropha and pongamia deoiled cakes and this study was carried out using research fund from Ministry of Nonconventional Energy Sources (MNES), India. The Bioenergy research Programs at the institute is actively working toward a secure and sustainable energy future for the state and nation. The centre strives to support a thriving Bioenergy industry using resources that can be produced in the country. The fuels produced during pyrolysis process can find applications, in automotive vehicles, driving aircraft engines and for electricity generation after suitable up gradation. The institute has research programs in biomass pretreatment and processing, biomass conversion technologies, biobased products, such as fuels, polymers, and chemicals, studies on the performance of compression ignition engines fuelled by the pyrolysis oils and studies on the application of solar energy for thermochemical conversion of biomass.
    Clean and Green Technology to overcome health risks associated with cutting fluids in manufacturing industries

    Machining operation plays a very important role in the manufacture of products. Huge quantity of cutting fluids are used in metal cutting industries for a variety of reasons such as improving tool life, reducing thermal distortion, lubricating the contact zones, preventing tool galling and seizure, improving surface finish and flushing away chips from the cutting zone etc. Despite the wide recognition of the aforementioned benefits, the negative aspects of cutting fluids become a serious issue for consideration in the recent years.
    Cutting fluids are normally petroleum based products and particularly complex due to the wide variety of chemicals that are added to the fluids to improve their physical characteristics and to prolong their usable life. Common additives include biocides, surfactants, and corrosion inhibitors. The types of additives as well as the amount of each additive are generally determined at the plant level. The elevated temperature at the cutting zone during machining process, vaporizes a portion of cutting fluid and produces harmful fumes which cause adverse effects to the workers in the shop floor and causes environmental pollution. Sometimes, the cutting fluid may be applied in the cutting zone in the form of mist. People exposed to large quantities of cutting fluids may have skin contact and they may inhale or swallow the mist particles of cutting fluid. The additives present in the petroleum based cutting fluids may cause the following diseases.
    Water-based fluids are subject to high levels of microbial contamination, including endotoxin-producing gram-negative bacteria, and the inhalation of endotoxin has been hypothesized to exert a protective effect against lung cancer. Skin disorders are common acute health effects from exposure to cutting fluids. Cutting fluids cause both allergic and irritant contact dermatitis. They often cause a cumulative insult type of irritant contact dermatitis. The problems associated with cutting fluids can be completely avoided by using dry machining. But it is very difficult to implement on the existing shop floor as it needs extremely rigid machine tools and ultra hard cutting tools. In order to alleviate the above-mentioned negative effects of cutting fluids, machining with minimal Cutting Fluid Application (MCFA) has been evolved. In minimal cutting fluid application, extremely small quantities (2 – 10 ml / min) of cutting fluid is injected in the form of ultra fine droplets at very high velocity (about 100 m/s) into the cutting zone which is also called as pseudo dry turning. For all practical purposes it resembles dry turning in achieving improved surface finish, lower tool wear by maintaining cutting forces and power at reasonable levels. In this aspect, the Department of Mechanical and Aerospace Engineering of Karunya Institute of Technology and Sciences provides excellent infrastructure and efficient faculty expertise through consultancy and testing in the areas of design and manufacturing namely, green manufacturing, damping of vibration through smart materials, optimization of machining parameters, analysis on tribological properties, fabrication and machining of composites. It also offers post graduate degree programme in collaboration with Central Manufacturing Technology Institute, Bangalore.
