      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。

        什么是壁面散热边界条件?....Fluent里面有么?

          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

            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?

              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!!!

                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?!
