摘要
通过在流道内安装三角形涡发生器可以产生纵向涡旋 .本文以场协同理论为指导讨论了在较低壁温 (小于 12 0℃ )条件下、Re在 80 0~ 70 0 0范围内 ,空气介质在强迫对流的情况下 。
Delta winglet vortex generators (DWVGs) can generate longitudinal vortexes in a channel. This paper studies the heat transfer enhancement between a heating surface and flowing air, in the context of forcing flow, within low wall temperature up to 120 ℃ and Re number from 800 to 7000. The field synergy theory is used to analyze the principle of heat transfer enhancement, which is caused by sticking DWVGs on the inner plane of the channel.
