摘 要: 扭带是一种最简单而又能使流体旋转的旋流发生器。采用三维数值模拟的方法研究在片式散热器一组通道内插入扭带对油侧传热性能的影响。结果表明:扭曲比的大小决定了含扭带管内的二次流强度,是扭带最重要的几何参数。随着扭曲比的减小,强化换热效果越来越好。
关 键 词: 热能工程;强化传热;片式散热器;扭带

Abstract: The twisted tape inserts are simple vortex generators which can make fluid rotate. In this paper 3-D numerical simulations were presented for heat transfer enhancement in oil-side of one channel with the twisted tape inserts of the panel-type radiator.It is found that value of twisted-ratio which is the most important parameter of twisted-tape determines the strength of second-flow in the channel. As the value of twisted-ratio decreases, the effect of heat transfer enhancement is better and better.
Key words: thermal engineering; heat transfer enhancement; panel-type radiator; twisted-tape
