- Abstract
In this paper, a performance analysis based on the entropy generation and thermal efficiency has been carried out for the irreversible dual cycle. The results show that the compression ratio versus entropy generation characteristic, the pressure ratio versus entropy generation characteristic, the compression ratio versus thermal efficiency characteristic, the pressure ratio versus thermal efficiency characteristic and the initial temperature versus thermal efficiency characteristic are approximately parabolic-like curves. There is negative linear relationship between entropy generation and environment temperature, between entropy generation and compression efficiency, and between entropy generation and expansion efficiency. There is positive linear relationship between entropy generation and initial temperature, between thermal efficiency and compression efficiency, and between thermal efficiency and expansion efficiency.
