摘要：
A Stirling heat engine model with heat resistance, heat leak, regenerator losses and mechanical friction losses is established and the shaft power and brake thermal efficiency performance of the engine is analyzed. It is assumed that the heat transfer between the heat reservoirs and the working fluid obeys the linear phenomenological heat transfer law q ∝ Δ (T-1). The analytical formulae about shaft power and brake thermal efficiency are derived. Detailed numerical examples show the effects of heat leak, regenerator losses and mechanical friction losses on the performance for the engine. The results obtained can provide theoretical instructions for the design and optimization of the Stirling engine.
