摘　　要：本文综述了熵产分析在传热与流动系统的研究与进展，包括对流传热传质、基本流动传热、换热器、热能贮存系统、绝热层布置等方面的研究与进展。As an analytic method for the second law of thermodynamics, the entropy-generation analysis related to heat transfer and fluid flow systems has been studied extensively, in which irreversible processes frequently occur. By means of the entropy-generation analysis, the irreversible loss a thermal process can be determined, and the irreversible-loss distribution of the system can thus been obtained. The design and operation of the system can thereby been optimized on the principle of minimum entropy generation. In this presentation, advances in the research on entropy generation in heat transfer and fluid flow systems were reviewed in detail. Research works were summarized on entropy-generation analysis applied in convective heat and mass transfer processes, heat exchangers, thermal storage systems, and layout of insulating layers etc.
