Ive been given a mini semester project "Simulate the Ericsson Cycle" in EES. We have to develop an interface for solving problems related to this cycle. I have already made an interface which takes Highest/Lowest Pressure and Temperature, gives out Heat In/Out, Work In/Out , Back Work Ratio, Efficiency & Entropy at 4 states. But this looks way too simple. I wanted to know if there is any other thing I can include in it. The cycle looks way too simple and little information is available online regarding it. Suggestions please !
