CFD Analysis on Exhaust System of a Car
Abstract: The pollution and global warming is due to air pollution. It is to be noted that air pollution is mainly caused by the toxic gases from the exhaust of the automobiles. Only 30% of the fuel is converted into energy source to run the engine remaining 70% of fuel is of un-burnt hydrocarbon, carbon monoxide and nitrogen oxides. From modified catalytic converter, noise level will decrease. Here, the performance of …

A Review on working of Gas turbine Operation
Abstract: The basic operation of a gas turbine is a Brayton cycle with air as the working fluid. Atmospheric air flows through the compressor, increasing its pressure. Energy would then be tried to introduce by spraying fuel into the air and igniting it to build a high temperature flow. This superheated steam gas enters a turbine, producing shaft work output in the process. The unutilized energy can be generated in the …
