ResumoA theoretical model for irreversible double resonance ESE (energy selective electron) heat engine system considering phonon induced bypass heat flow is proposed. The thermodynamic performance of the electron engine is optimized and the optimal regions of performance parameters are determined with finite time thermodynamics theory. The influences of heat leakage and structure parameters of the electron system on the performance are discussed in detail by numerical examples. It reveals that the characteristic of power versus efficiency behave as loopshaped curves in spite of the heat leakage which will always decrease the efficiency of the electron engine. Through properly choosing design parameters, the ESE engine can be designed to operate
optimal conditions with maximum power or efficiency. The obtained results have academic guidelines for
designing practical electron heat engines.
