Title : A Future Technology of Automobile Engine That Runs on Compressed Air as a Fuel
Country : India
Authors : B. R. Singh, O. Singh

Abstract: Heavily release of tail pipe emissions is the biggest challenge to 21st Century developments, causing serious threat to Global Warming. Worldwide fast utilizations of transport sector alone releases billion tones of excessive carbon dioxide in the atmosphere through tail pipe emissions. It is also leading to fast depletion of hydrocarbon fuel. On account of such challenges, continued researches are being carried out to supplement the energy by renewable resources and alternate energy to sustain hydrocarbon fuel. Now a days the major thrusts are being opted for utilization of wind energy, hydro-power, tidal and nuclear power generation. Simultaneously efforts are also made towards storage of the energy and appropriate conversion system and its better utilization. This paper focuses on study of energy storage and its re-utilization systems. at appropriate period of time. In this, a special focus is laid upon use of compressed atmospheric air as a viable alternative energy source. Such energy sources are preferred to be used as clean and zero pollution energy source that can help in mitigating the global warming.

Title : Optimization of Cutting Parameters in Boring Operation
Country : India
Authors : A.M.Badadhe, S. Y. Bhave, L. G. Navale

Abstract: In the present work an attempt is made to select the combination of optimum cutting parameters which will result in better surface finish. Machining with optimum cutting parameters will result in minimum machining time and hence increasing the productivity. Four parameters viz. spindle speed, feed, depth of cut and length to diameter (L/D) ratio of boring bar has been taken as control factors. The cutting trials were performed as per Taguchi 34 (L9 ) orthogonal array method to deal with the response from multi-variables. AISI 1041 (EN9) carbon steel was used as a job material which was cut by using standard boring bars of various sizes each having a tungsten carbide inserts of same insert radius. The Analysis of Variance (ANOVA) was carried out to find the significant factors and their individual contribution in the response function i.e. surface roughness.

Country : India
Authors : B. Venkatesh, S.V.Prabhakar Vattikuti, D.V. Ramanareddy, S. Naresh Kunar, V.Kamala, AMK Prasad

Abstract: Gears are one of the most critical components in mechanical power transmission system and they are advantage over belt, wire, rope and chain drives. Gears are most commonly used for power transmission in all the modern devices. They have been used extensively in the high-speed marine engines. Gear design has evolved to a high degree of perfection; the constant pressure to build less expensive, quieter running, lighter weight, reliable, less cost and more powerful machinery has lead to steady change in gear design. Today, the most significant new gear developments are in the area of materials. The objective of the present work is to focus on investigating the effects of face width, gear ratio, normal module, speed and helix angle on bending stress of steel alloy (40 Ni2 Cr1 Mo28) helical gear for marine applications.

Title : Investigation of Concrete Solar Collector: A Review
Country : India
Authors : A. A. Keste, S. R. Patil

Abstract: Concrete collectors offer a promising and viable solution over the conventional collectors used today. Concrete has the dual advantage of having high storage capacitance as well as its freedom from corrosion due to alkaline nature of cement. Concrete is the most promising material among low cost energy materials as it is a very common building material and its technology is well established. The present work reviews the literature produced so far on concrete collectors with the aim of sharing the information here gathered for future developments. Therefore it is planned to use metal fiber reinforced concrete for storage cum insulator base of solar collector. Metal fibre reinforced concrete have the advantage of increased thermal conductivity due to inclusion of metal fibres. The proposed work is concerned with the experimental setup of a cheaper and economical 2m X 1m solar concrete collector and analysis of its performance. The objective of present work is to find out daily efficiency and average temperature of the output hot water.

Title : A Descriptive Study of the Constructional Features of Evacuated Tube Solar Water Heating System
Country : India
Authors : A. A. Satam

Abstract: Renewable sources of energy are anticipated to play a significant role in energy generation in India in the future. The word itself ―Solar, describes that we are dealing with some renewable energy source for a hot water system. The solar hot water system has been a popular throughout the world as it is cost effective and easy to maintain. The system is always successful when its efficiency level increases. Solar water heating (SWH) systems are gaining popularity in India with increasing number of affluent population in society and environmental concerns from seemingly unchanged reliance on fossil-based fuels. The penetration of these systems and technologies into Indian markets is a welcome development; however there is a need for the method of assessment of their thermal performances. Evacuated tube collector system is one of the effective methods of solar water heating systems. The usage of evacuated tube collectors is increasing day by day. This paper describes the evacuated tube solar water heating system with respect to its constructional features.

Title : Potentials of Micro-EDM
Country : India
Authors : N. B. Gurule, S. A. Pansare

Abstract: Presently manufacturing industries are facing challenges from difficult-to-machine materials viz. Super alloys, ceramics and composites which require high precision and surface quality thereby increase machining cost. In addition to this rapidly developing technology aims to develop products in miniaturized compact volumes with more functions are embedded in the products. This requires advancement of micro manufacturing; hence industrial research on micro-machining has become considerably important and widespread. To meet these challenges, non-conventional machining processes are being employed to achieve higher metal removal rate, better surface finish and greater dimensional accuracy, with less tool wear. In this context, micro-EDM is one of the topics towards developing micro manufacturing. Micro-EDM is a newly developed method to produce micro-parts in the range of 50 -100 μm. It is an efficient machining process for the fabrication of a micro-hole. Micro-EDM process is based on the thermoelectric energy between the workpiece and electrode. There are many electrical and technological parameters of micro-EDM process which are decisive in the machining characteristics and affect geometrical shape and surface quality of the machined parts. This paper describes the potentials of micro-EDM process, the micro-machining principles, characteristics, process parameters and recent developments.
