| Abstract: | An irreversible simplified model for Dual cycles is established in this paper, which considers the effects of the finite-time evolution of the cycle's compression and power strokes and the friction in whole cycles .The relations of the power output versus the compression ratio and the thermal efficiency versus the compression ratio are derived. The loop-shaped power-versus-efficiency curves obtained by our modes are common to almost all real heat engines. |
