急询iomega兄
记得前一段时间,看到你关于某个问题的回复,说在ansys帮助文件里面找到了冷却水的膜换热系数的换算公式,在哪找到的,快告诉我,急用。就是,已知水的运动粘度,管道尺寸,水的密度,导热系数,普朗特常熟等,去求换热系数的那个公式,一定要ansys帮助文件的原文,告诉我在什么位置即可,谢谢!
当然了,如果其他兄弟有知道的,也希望不吝赐教!谢谢!

Hehe, the h is determined by the flow states: internal or external flow, developing or developed stages (the distance from entrance), cosntant heat flux or temperature from wall. Basically you will get the h in the form of Nusslt number. I don't think you can find it on Ansys help file( I don't ahve ansys on my pc now), but you can find it in typical convective heat transfer books.
