摘　　要：对换热器在多种冲刷方式下采用粗糙肋面强化对流传热的综合性能指标评价方法进行了讨论 ,并提出了评价通用方程 .The evaluation methods for the integrate performance of heat transfer enhancement by using rough surfaces in heat exchangers with different flow forms have been investigated. A general evaluation equation has been derived. This equation can provide proper evaluations for the performance of heat transfer enhancement including different flow forms and the influence of the Re number.
