Evaluation of the optimum pressure of the intercooler and the regenerator in the Bryton cycle based on exergy and energy analysis

In this paper, energy and exergy analysis has been done for irreversible Brayton cycle with regenerator, reheater, and intercooler. In this work, the influence of the different parameters such as the efficiency of cycle’s components surveyed based on the first and the second laws of thermodynamics. The lost exergy in the different components and the total lost exergy of the irreversible Brayton cycle are calculated under several conditions. Also, the optimum pressure of the intercooler and the reheater are obtained under different conditions. To obtain the optimum pressure, irreversible Brayton cycle with regenerator, reheater, and intercooler is simulated in engineering equation solver software and optimum pressure is obtained based on the first and the second laws of thermodynamics in each simulation. The obtained optimum pressures are compared with the geometric mean of the low and the high pressure of the cycle in each simulation.
