Determining performance of an irreversible nano scale dual cycle operating with Maxwell–Boltzmann gas

•Irreversible nano scale irreversible dual cycle is investigated.•Maxwell–Boltzmann ideal gases are used as working fluid.•Different methods are used and compared each other.•Numerical results are presented and discussed.

In last decades, nano technology developed. Since, nano scale thermal cycles will be possibly used in near future. In this study, a nano scale irreversible dual cycle was analyzed thermodynamically. Ideal Maxwell–Boltzmann gas is used for working fluid in the system. He4 is chosen as working fluid. Results are obtained as numerically. In calculations, different thermodynamic performance evaluation methods are applied and these methods are compared each other to determine the most convenient optimization way.
