3.1Mesh motion equations Let us consider a domain Dold which represent the mesh confi guration at a time told. This domain is moving through imposed condition at the boundary for 5 instance imposed displacement or velocity. The question is to build a new valid mesh Dnewat tnew= told+t ...

方腔流可以反映出不同雷诺数条件下的流场特性,并且流场中包含了涡旋、二次流、复杂三维流动、不稳定层流、过渡流和紊流等多种现象,成为研究复杂紊动流场最为理想的物理模型,也是验证数值模拟方法准确度和效率的标准(张金凤,2015)。 图3-1顶盖驱动方腔流动模型,左为OpenFOAM Tutorial给出的计算模型,右图为实验模型 ...
图3-1顶盖驱动方腔流动模型,左为OpenFOAM Tutorial给出的计算模型,右图为实验模型 在OpenFOAM中求解这个问题主要分为三个环节:前处理()——求解——后处理。首先将官方指南设置好的算例放入RUN所在的文件夹下,在BlueCFD终端中输入: 1cd $FOAM_RUN 2
