Recently,the calculation of ideal value was involved in the main mathematical model of isentropic expansion process,so compared with the actual value,the results had a certain error.Deriveing the mathematical model of isentropic expansion process based on Φ function by using the definition type of process efficiency.Compared with the results from the mathematical model of isentropic expansion process based on entropy and the mathematical model of isentropic expansion process based on ideal value,concluded that:(1) accuracy can be improved when applying the mathematical model of isentropic expansion process based on Φ function;(2) application of the mathematical model of isentropic expansion process based on Φ function is simple,and can greatly improve the programming efficiency and computational efficiency.
