传热边界



  • 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。


  • 管理员

    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。
