“What are the common assumptions for analyzing Power engines?”

 

Power engines are very complex machines. As such, we will have to simplify them a bit when performing analysis. So how can we use our engineering mindset to solve this problem? Well, let’s make some assumptions. First Since these systems are fluid based, and the air is the simplest fluid to analyze, let’s say that air is the primary working fluid. Second, let’s say that all processes are ideal and reversible. Third, have combustion is modelled by a heat addition process. Fourth finally, let the exhaust process is a heat rejection process. These are known as the Air Standard Assumptions and are some of the most fundamental aspects of thermodynamics
