| Abstract: | On the basis of a generalized irreversible
Carnot engine model with the losses of heat resistance, heat leakage and internal
irreversibility, the angular speed-dependent performance of the engine is
analyzed and optimized with Newton’s
heat transfer law Q A(T) between the working fluid and the
heat reservoirs. The relations among the dimensionless power output, efficiency
and the angular speed of the heat engine, the optimal angular speed
corresponding to the maximum power output and the maximum efficiency are
derived. Numerical examples show the effects of the heat leakage and the
internal irreversibility on the angular speed-dependent performance of the
engine. The results can provide guidelines for selecting appropriate working
point of heat engines. |
