The help file of CFX solver theory guide says that for the mixture model the interfacial length scale must be specified. And an equation about calculating this d.ab from (r.a, r.b,d.a,d.b) is provided.
However, when both fluid are treated as continuous fluid, how do I get the d.a and d.b? |

I do not know how to specify it. But if you do a sensitivity study you might find it does not matter anyway. If not you better work it out.

Hi Tommy
Did you find out how to define mixture length scale for two continuous fluids? |

I haven't used CFX for several months. If you can leave an email here, I'd like to send you some pictures that illustrates the effects of various mixture length or particle diameter settings. |
