对多纵向涡对管内湍流换热和流阻特性进行了数值分析。
The characteristic of turbulent heat transfer and flow resistance with multi-longitudinal vortexes in tube is numerically analyzed.
结果表明，多纵向涡可明显强化管内湍流换热，其流阻增加与换热增强相当。
The results show that the multi-longitudinal vortexes could enhance the turbulent heat transfer in tube markedly and the flow resistance increase is similar to heat transfer enhancement.
对多排纵向涡发生器对竖直平板自然对流的强化效果进行了研究。
This paper focuses on the study of heat transfer enhancement in the nature convection in the vertical plat by using delta-winglet longitudinal vortex generators arranged in rows.
