为了验证Fluent中wall的thermal边界条件的具体含义,设计了一个简单的圆柱体,内部为温度1000℃的空气,壁面厚度0.05m,看不同边界条件的结果如何: (1)关于几何模型和网格划分 下部为入口,直径2m;上部为出口,直径2m;高度2m。采用O-GRID网格进行划分,总数量1600个。 (2)壁面选择convection,heat transfer coefficient设置...
A：如果不开启湍流模型，即只计算层流，则在后处理时只有Surface Heat Transfer Coef.和Wall adjacent ...
A: 应该采用Surface Heat Transfer Coefficient来查看壁面的对流换热系数。Surface Heat Transfer Coefficient...
Fluent中后处理部分在xyplot里wall flux下有surface heat transfer coefficient和wall func heat transfer ...
Guest Posts: n/a Dear all, I have a problem of wall temperature setting. As we know, one can choose the wall heat transfer model as "heat transfer coefficient", then one can input a proper heat transfer coefficient and an outside temperature. CFX will caculate the wall temperature by the...

Furthermore, the system demonstrated significant insulation levels with a mean heat transfer coefficient of 0.8 W/m2.K. Besides, the WBTW system demonstrated significant efficiency as it reduced the thermal load by as high as 42.6% alongside harvesting 435.7 kWh of energy in a year. As can...
Heat flux in OpenFOAM is: qDot = alphaEff| v-> f * grad(h) but i am not sure about fluent. here is the complete case set: http://cdn.anonfiles.com/1336156429443.zip Upon generating results which is comparable to fluent, one can say that OpenFOAM wall functions a...
