您好,我想再问您一个问题:怎么在fluent中把边界条件中的heat transfer coefficient的值设置为一个变量?需要用udf中的define_profile宏吗?... 是这样的,fluent的参数设置条件里,只有常数和曲线不用编写程序,剩下的都需要UDF来实现的。希望能够帮助您, 16 1 2 ››猜...
Re: Heat Transfer Coefficient #3 Sung-Eun Kim Guest Posts: n/a Jonas, The "bulk temperature" can be unequivocally defined in the case of simple flows where you have a dominant flow direction (e.g. duct flows). However, I and we developers have really hard time to understand what you ...
在对流传热问题中，壁面的对流传热系数（h）的求解是关键。本文将聚焦于管内流动的表面换热系数求解过程。计算公式为：h=q/（Ts-Tref），其中q为热流密度，Ts为壁面温度，Tref为参考温度。在Ansys Fluent中，可通过“Reference values”面板自定义设置参考温度。注意：若流动处于充分发展状态，即整个计算...
