Dear all, I met a problem when trying to model the high Pr number fluid flowing in a heating pipe. The fluid is water-glycol mixture with Pr from 50-60. The Pr varies with temperature. In Kays book it said that no good near wall models for high Pr fluid. Can any body tell me how to do this in FLuent? Is there any papers related with this? The turbulent number is around 10000. Thanks a lot
I have tried standard wall function, enhanced wall treatment and non-equilibrium wall, none of them seems to give me the right answer. |
