Abstract
A more realistic cycle model is established for discussing the performance of the Stirling heat engine with regenerative losses. The power output is adopted as an objective function for optimisation. The maximum power output and the corresponding efficiency of the Stirling heat engine are derived. The effect of regenerative losses on the efficiency at maximum power output is expounded. The times of four processes in the Stirling cycle are allotted optimally. Some new conclusions are obtained.
