Using EES (or other) software, study the effect of varying the temperature after the constant-volume heat addition from 1500 K to 2500 K. Plot the net work output and thermal efficiency as a function of the maximum temperature of the cycle. Plot the T-s and P-v diagrams for the cycle when the maximum temperature of the cycle is 1500 K.
Prob. 9-13
An air-standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes:
1-2 Isentropic compression from 100 kPa and 22oC to 600 kPa
2-3 v = constant heat addition to 1500 K
3-4 Isentropic expansion to 100 kPa
4-1 P = constant heat rejection to initial state
