摘要:
以反映热机功率与熵产率之间最佳折衷的生态学准则为目标,根据生态学优化方法研究传热规律服从Q∝Δ(T n)时不可逆卡诺热机生态学最优性能.在内可逆模型基础上,用常数项q表示热漏流率,用常数项Φ表示除热阻和热漏以外的其余不可逆性,导出了传热规律服从Q∝Δ(T n)时广义不可逆卡诺热机生态学优化性能.通过数值计算对不同损失不同传热规律情况下的热机生态学性能变化规律进行了比较分析,本文结果对实际热机的设计工作具有一定的理论指导意义.
Abstract:
Based on the endoreversible model, the optimal ecological performance of an irreversible Carnot engine with the losses of heat-resistance, heat leak and internal irreversibility, in which the heat transfer between the working fluid and the heat reservoirs obeys a generalized law Q∝Δ(T n), is derived by taking an ecological optimization criterion as the objective, which consists of maximizing a function representing the best compromise between the power and entropy production rate of the heat engine. Some special examples are discussed. A numerical example is given to show the effects of heat transfer law, heat leakage and internal irreversibility on the optimal performance of the engine. The results provide certain theoretical guidance for the design of practical engine.
