Thermal Simulation and an Analysis on an Exhaust Gas of a Teg Model using Fluent

Abstract

As the First law of Thermodynamic says “energy is directly proportional to work done” and law of conservation of energy “Energy can neither be created nor can be destroyed, it can only be transformed from one form to another”. Unfortunately any energy policy that produces improvements in the short term is often one that destroys the environment in the long run. It is a universal truth that no exponential growth will last forever. In other words, the global net impacts have heavy consequences on the entire planet’s inhabitants. Here a study of conservation is being followed. (TEG) Thermo-electric generator is an Electro-mechanical device which converts, heat energy into electrical energy. This waste heat if recovered can be used for various other applications. The TEG used in heat power output and system efficiency works as a heat exchanger. Here the device has been engaged into exhaust system for reuse of heat energy for further use of energy in an automobile or a generator. A model is developed in UNIGRAPHICS NX and updated into ANSYS 16.2 software for this purpose. Air is used as a Fluent, having velocity 1 m/s, 2 m/s and 3 m/s. Fluent workbench is being engaged for the summation of results. The parameters are set and are simulated in double precision. The simulation is based on Temperature and thermal heat transfer is studied.
