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 …
