摘要
建立一类空气标准Dual循环的不可逆模型 ,考虑压缩过程和做功冲程的有限时间特性和循环的摩擦损失对其性能的影响 ,推导出功率、效率与压缩比关系的解析式 .结合数值算例 。
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.
