在Zone中选中搅拌桨blade,点击Edit,在弹出的对话框中Wall Motion下方选中Moving Wall,右边的Motion默认Relative to Adjacent Cell Zone不变,即相对运动,下方选中Rotation,Speed为0(与搅拌轴共速,故相对轴运动速度为0) 交界面配对。点击Mesh Interfaces,弹出对话框如下。前面在划分网格时一再强调交界面的名字不可以相同,...

Also how uniform is your fluid temperature? The net radiation flux is zero; to be adiabatic the wall only has to be the same temperature as the fluid adjacent to the wall. There may be a very sharp gradient in temperature near the wall which allows for a substantial difference between bulk...
Wall thickness适用于模拟两个流体区域之间的金属片、固体区域上的涂层或两个固体区域之间的接触阻力等场景,而shell conduction适用于需要计算三个方向的热传导、导热系数可以是非常数或需要设置多层的场景。根据研究问题的不同,可以选择合适的方法。 如下图所示,当我们用fluent计算传热时,我们给壁面施加一个热边界条件...
