摘　　要：在对管内受迫对流换热过程进行火用经济分析的基础上，提出了一项评价管内强化传热性能的火用经济指标——强化传热性能费用因子σ。该指标不仅反映了采用强化传热措施后传热能力的改善。Based on the exergy economic analysis of convective heat transfer through a duct,an exergy economic criterion σ which is defined as enhanced heat transfer performance cost factor is put forward.It is shown that σ can not only illustrate the improvement of heat transfer ability,but also the variation of all cost including production cost after heat transfer enhancement measure is adopted.
