The domestic air coolers, which are cost effective, play a positive role in providing human comfort during hot weather [5]. However the performance is dissatisfactory in the high humid regions. This project paves a way to investigate the performance of air cooler integrated with phase change material (PCM) by eliminating the problem of rise in humidity that usually encountered in the conventional air cooler. The objective of the present invention is to provide cooled air to maintain the room temperature according to the requirement. This type of air cooler consists of heat exchanger, air duct and variable speed fan. Before the use of the mobile air cooler, the PCM filled heat exchanger tubes are kept in a domestic refrigerator for few hours depending on the requirement. During this period the phase change material in the tubes are get converted to solid and stores cold energy as latent heat of fusion. This is known as cold energy charging process. The charged PCM filled heat exchanger tubes are to be fitted to the heat exchanger whenever the customer needs to use this “Air Cooler with Thermal Storage”. When “Air Cooler with Thermal Storage” is switched on, the atmospheric air gets circulated by the fan passes through the heat exchanger and finally air gets cooled by the Ice/phase change material. During that time, The Ice/phase change material absorbs the heat present in the air and changes its phase from solid to liquid. This process is known as cold energy discharging process. This cooled air is focused to the area where occupants are present and cooling can be achieved locally.

In recent times disposal of industrial waste become a major issue for researchers. Red mud is an industrial waste produced during alumina extraction. Trials have been made by scientists and engineers for effective utilization of this waste for domestic and industrial applications. The raw material used in this study was collected from Damonjodi, Orissa. In the current research, an epoxy based hybridized composite material comprising of glass fiber, jute fiber and red mud as filler material has been developed and the mechanical properties such as flexural strength, tensile strength and density of the composite have been evaluated. From the analysis of the results obtained from the tests conducted on the composite material, it is observed that the flexural strength, tensile strength and density of the material increases with increase in the number of layers of reinforcement. The results from the present investigation shows that the developed composite can be effectively used for low load bearing application and can also be used for different applications in automotive industries.

This paper investigates the effect of using unleaded gasoline blended with ethanol and methoxy ethanol blends on spark ignition engine (SI engine) performance, and exhaust emission. A four stroke, single cylinder SI engine was used for conducting this study. Performance tests were conducted for fuel consumption, volumetric efficiency, brake thermal efficiency, brake power, engine torque and brake specific fuel consumption, while exhaust emissions were analysed for carbon monoxide (CO), Hydrocarbon (HC), and Oxides of nitrogen (NOx) using unleaded gasoline and additives blends with different percentages of fuel at varying engine torque condition and constant engine speed. The result showed that blending unleaded gasoline with additives increases the brake power, volumetric and brake thermal efficiencies and fuel consumption. The CO and HC emissions concentrations in the engine exhaust decreases while the NOx concentration increases. 7.5% of methoxy ethanol and 10% ethanol addition to gasoline gave the best emission control and performance among all fuel blends.

Diesel engines are increasingly becoming important because of their fuel economy and efficiency. Now-a-days, ceramic coating over the cylinder head, valves and the piston top surfaces are provided for thermal insulation. These thermal barrier coatings reduce the heat transfer from the combustion chamber to the cooling jackets and to the atmosphere. This paper presents the investigation of the temperature distribution over the cylinder head, valves and the piston resulting from coating those using Partially Stabilized Zirconia (PSZ) thermal barrier coatings. This analysis is based on the fact that coating thickness affects the heat transfer and temperature distribution in the cylinder head and piston. A 3-D Finite Element Analysis (FEA) using ANSYS is performed to evaluate the temperature distributions over the cylinder head, inlet valve, exhaust valve and the piston. Based on the analysis, it can be concluded that a coating of PSZ over the combustion chamber increases the temperature over the inside the combustion chamber and reduces the heat rejection to the atmosphere.

Safe road journey is necessary to every human being. Utilisation of private vehicles-two wheelers, four wheelers, school buses, vans, college buses, industrial vehicle, public transport-MTC bus, Commercial vehicles, water lorries, sand lorries, restaurant vehicles, vegetables and milk vans are increasing in manifold every day in Tamilnadu in particular Chennai metropolitan and sub-urban. A road transport is playing an important role for economic development. At the same time every day we are facing human loss, social and economical loss due to road accident. There are many reasons for road accident such as increasing vehicle population, urbanization, drunken drive, rash driving, poor licensing system, lack of infrastructure, less space availability corresponding to vehicle population in metropolitan, violation of road safety rules, poor drainage system during rainy season, using cell phone on driving. The Six sigma technique i.e. DMAIC principle (Define, Measure, Analyze, Improve, and Control) is an effective quality control tool. The objective of this study is to identify the different reasons for idle time (traffic jam) and road accidents in Chennai, India through DMAIC principle-six sigma technique and suggest a possible solution for this problem.

A two-stage Pulse Tube Cryocooler (PTC) is developed with a no-load temperature of 2.5K in the second stage and 67K in the first stage at an operating frequency of 1.6Hz. The system gives a cooling power of 250 mW at 5K in the second stage. Several PTCs have been experimentally studied by varying the dimensions of the pulse tubes and the regenerators, as well as the regenerator materials to arrive at the best configuration. Studies conducted with several configurations indicate that the Pulse Tube dimensions are more critical compared to those of regenerator to achieve low temperatures. Also the system performance improved with the proper design of cold end heat exchangers with minimum flow impedance. These results along with cooling power characteristics of the cryocooler are discussed in this paper.

Polarization characteristics of the processes of Cu, Co and Cu-Co alloy electrodeposition from ammonium sulphate containing supporting electrolyte and their morphologies are investigated as a function of Cu2+ and Co2+ ions concentrations. By application of energy dispersive spectral analysis, (EDSA), including X-Ray analysis and SEM, data are obtained about the morphology and element composition of the deposited Cu-Co alloy coatings. The optimum electrolyte composition and the deposition potentials for production of quality coatings are determined. It is found that the conditions leading to cobalt content increase in the alloy result in improvement of the Cu-Co coating structure they are more fine-crystalline and homogeneous. These are compositions in the ranges: for CuSO4 up to 25g dm−3 and for CoSO4 from 25 to 50 g dm −3. It is found that in the developed electrolyte the maximum Co content is about 50–55.

Convective heat transfer rate of traditional fluids are very lower than solid particles. The use of additives is a technique applied to enhance the heat transfer performance of base fluids. Suspension of millimeter or micrometer sized solid particles conduct more heat than the base liquids. The major problem with the large particles is rapid settling in fluids, abrasion and clogging. The fluids with nano-sized solid particles suspended in them are called nanofluids. It can overcome the above mentioned issues. The suspended metallic or nonmetallic nanoparticles change the transport properties and heat transfer characteristics of the base fluid. Nanofluids are expected to exhibit superior heat transfer properties compared with conventional heat transfer fluids. Furthermore, nanofluids are expected to be ideally suited in practical applications as their use incurs little or no penalty in pressure drop because the nanoparticles are ultrafine, therefore, appearing to behave more like a single-phase fluid than solidliquid mixture. Mixing nanoparticlesin a conventional fluid has a dramatic effect on the fluid thermo physical properties. The purpose of this article is to summarize the published subjects to the forced convective heat transfer of the nanofluids.

The effects of Methyl-Tetra-Butyl-Ether (MTBE), as an additive, on the performance, combustion and the emission characteristics of a compression ignition (CI) engine are investigated experimentally. The experimental set-up consists of a diesel engine coupled with an eddy current dynamometer, AVL Di-gas analyser, AVL smoke meter and a data acquisition system is used. The di-gas analyzer is used to measure NO, CO and HC in the exhaust gases and the smoke meter is used to measure the smoke coefficient of the exhaust gases. The whole investigation is carried in two phases using the neat diesel in the first phase and the MTBE blended diesel fuels in the second phase. The MTBE blended diesel fuels are prepared in the varying proportions of MTBE (2, 4 and 6 %); subsequently the stability characteristics of the fuels are studied under static conditions. All the experiments are conducted at a constant speed of 1500 RPM by varying the brake load and the data obtained from the experiments are used to evaluate the performance and the combustion characteristics while, the emission characteristics are directly measured. The experimental results revealed that a significant improvement in the performance and appreciable reduction in the emissions for the MTBE blended diesel fuels on compared with neat diesel. The combustion analysis is supported the outcome on the performance and emission of the engine.
