fluent周期边界条件(cyclic boundary condition)是指在求解流体力学问题中,当空间分解可用时,采用周期性的边界条件,以减少计算量。它是一种特殊的边界条件,其中一个物理边界处的运动量可以由另一个物理边界处的运动量决定。因此,当计算大块区域时,可以采用周期性边界条件,该边界条件可以将所有的边界整合起来,使得计算变...
You are using cyclic boundary conditions? I tryed to get them running for different very similar cases, namely a straight pipe and a channel flow. Both of them did not converge properly no matter what numerical settings I used. I eventually used the "mapped" boundary condition instead ...

So right now my model is a closed domain, which results in the uprising of the resin level as the four cyclic walls push downwards. Of course, this model is only a tiny cutout of the real situation, in which thousands of fibers get impregnated with resin. In the real impregnation process...
Note that while FLUENT does not require a cyclic branch cut in an O-type grid, it will accept a grid that contains one. Figure 1: 机翼的四边形结构网格 Figure 2:非结构四边形网格 Figure 3: 多块结构四边形网格 Figure 4: O 型结构四边形网格 Figure 5: 降落伞的零厚度壁面模拟 Figure 6: ...

FLUENT 提 供了两种类型:一类是流体经过周期性重复后没有压降(Cyclic );另外一类有压降 Periodic )。叶轮机械的性能计算采用单流道模型,就是采用周期性边界条件,用以减少全 ( 局网格量。 15.内部边界面 内部边界面只在单元的面上定义。一般内部边界面的厚度为零,内部边界面上的变量可 以突变。内部边界面用以...
The motions can either be: Translational – such as the cyclic oscillation of liquid in a tank or a train moving through a tunnel. Or Rotational – which is perhaps the most common. Examples include flows though turbomachines (pumps, turbines, compressors, and related equipment), electric ...
the route leading to fuel NOx formation and destruction is still not completely understood, different investigators seem to agree on a simplified model: Recent investigations 94 have shown that hydrogen cyanide appears to be the principal product if fuel nitrogen is present in aromatic or cyclic ...
