请教一个多组分的问题

brookswen

我目前在做过热蒸汽冷凝(含微量空气),两种组分在计算域里应该哪种用transport equation?哪种用constraint? 采用了transport equation组分的kinematic diffusity又该取值多少呢?谢谢

您的这个问题我也很感兴趣，在fluid model 和solve control里面有很多选项，虽然在solver theory 里面有详细的说明，但是在具体操作上还是有很多疑惑。
很想找人讨论一下，要是愿意的话，我们可以联系：0532-83786782

now i can give you right answer ,that is,the predominat composition should be set as constraint,the other should be set as transport equation.
this was described in cfx-theory
