Abstract: The objective of this work is the optimization of the cutting parameters for turning AISI 316 stainless steel to achieve the better surface finish using Taguchi's methodology. Taguchi Parameter Design is a powerful and efficient method for optimizing quality and performance output of manufacturing processes, thus a powerful tool for meeting this challenge. This work discusses an investigation into the use of Taguchi Parameter Design for optimizing surface roughness generated by a Turning operation. In this method, four control factors viz. cutting speed, feed rate, depth of cut, three different cutting fluids (sherol B, sherol ENF..........

Keywords: Cutting parameters, turning, Surface roughness,Cutting fluids, Taguchi method.

Abstract: Concentration of gaseous pollutant and particulate matter are the major cause of respiratory disease and deaths. The dust pollution is serious matter almost in all cities of Maharashtra. This paper deals with the results of ambient monitoring of Aurangabad city for particulate matter, sulphur dioxide and nitrogen dioxide. The sulphur dioxide concentration is measured by Modified West and Geake Method whereas nitrogen dioxide is measured by Modified Jacob and Hochheiser method. The results shows a very high concentration of particulate matter, however sulphur dioxide and nitrogen dioxide were within the permissible limits.

Abstract: The alternative energy sources are new option in front of world to overcome energy crisis and pollution related issues. The solar energy, wind energy and bio mass are three major sources and out of these three energy sources solar energy is the easiest source to extract useful energy because the wind energy can be useful particularly in coastal area where there is high wind velocity and energy extraction bio mass needs either chemical conversion or thermo chemical conversion process. The objective of present work is to developed solar distillation system consists of wax as phase change material to improve the thermal performance.

Keywords: Alternative energy sources, solar energy, solar distillation.

Abstract: Exhaust manifold is one of the most critical components of an IC Engine. The functioning of exhaust manifold is complex and is dependent on many parameters viz. back pressure, exhaust velocity, scavenging etc. In the present work, the performance of a four-stroke four cylinder gasoline engine exhaust manifold have been analysed using three different fuels - gasoline, alcohol, and LPG for the estimation of flow characteristics, thermal characteristics, and minimum back pressure. The manifold modelling is done in Creo2.0 followed by meshing and analysis in ANSYS. The LPG fuel gives minimum back pressure, temperature and velocity being approximately in the same range for all three fuels viz. gasoline, alcohol and LPG. Thus, LPG can be considered as a suitable alternative for gasoline in terms of minimum back flow in manifold.
