传热边界

[zhanghan]

我在buoyantBoussinesqSimpleFoam下计算不可压缩流体温度场和流场，涉及到壁面散热边界条件。
请问各位我将怎样设置壁面散热这个边界条件呢。

[赵一铭]

什么是壁面散热边界条件？....Fluent里面有么？

[zhanghan]

我没有用过fluent，在CFX中是热通量，好像也可以说成热流密度，单位是W/m2

[李东岳]

看看这两个帖子里面有说这个热通量边界条件：
http://www.cfd-china.com/topic/113/均一的边界条件如何设置
http://www.cfd-china.com/topic/804/模拟管道内温度分布

恩？好像是一个人？

@李东岳

是的!!!!!
但是 计算过程中出现了一个问题如下,我不知道该怎么办了,麻烦您帮我看一下,万分感谢!!!

@chixt

以上是我设置这种边界条件后出现的问题。

写none的关键词后面应该改成directionalSolidThermo、fluidThermo、lookup、solidThermo中的一个吧？！
