FINITE-TIME THERMODYNAMIC SIMULATION OF PERFORMANCE OF JOULE-BRAYTON CYCLE WITH VARIABLE SPECIFIC HEATS OF WORKING FLUID

Abstract

A finite-time thermodynamic modelling and simulation of irreversible Joule-Braytoncycle has been developed taking into account the variabilityof specific heats for working fluid due to temperature variation. The effect of parameters on the engine was discussed, which is the internal irreversibility. A program was developed by using MATLAB software to perform the necessary calculations ofthermodynamic model. According to the results obtained, it was found that the results obtained from the thermodynamic model compared with the results obtained from experiments are convergent, and may be used in actual engine designs and applications.
