摘要：
The finite-time thermodynamic performance of a generalized Carnot cycle, in which the heat transfer between the working fluid and the heat reservoirs obeys a generalized law Q proportional to(DeltaT)(m), is studied. The optimal configuration and the fundamental optimal relation between power Output and efficiency of the cycle are derived. Some special examples are discussed. The results can provide some theoretical guidance for the design of practical engines. (C) 2003 Elsevier Ltd. All rights reserved.
