| 摘 要： | 数值模拟了波峰尖端分别为尖角和平面的三角形黄铜缩放管流动和换热状况,获得两者换热效果相近,但波峰尖端为尖角的缩放管比为平面的缩放管压降大、换热与流动阻力综合效果欠佳的结论,为三角形缩放管的设计提供参考。

| Abstract: | Both flow and heat transfer in triangular brass convergent-divergent tube which boasting of cutting-edge peaks with sharp corners and plane was studied with numerical simulation method.The result show that their heat transfer effects are alike,but the pressure drop of the convergent-divergent tube with sharp corners around the peak becomes larger than that of the tube with plane around the peak,together with a poor heat transfer and flow resistance,this provides the reference for designing triangle convergent-divergent tubes. |
