Abstract:
A finite-time thermodynamic modeling and simulation of irreversible Diesel cycle engines has been developed taking into account the variabilityof specific heats for working fluid due to temperature variation.
The effect of four different parameters on the engine was discussed, which are: the internal irreversibility, the heat losses, the friction losses and the cut-off ratio.
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.
