Hey all,
I wanna build a two fluid solver for research of mixing two different fluids (e.g. methan + air). I can use the reactingFoam solver but thats too expensive (calculation time). I made a scalarRhoSimpleFoam which gives good results but I am mixing Air/Air. Inlet 1 = scalar = 0 || inlet2 = scalar = 1. So I consider the mixing of the added conserved scalar but due to the same density of the inlets (air / air) there is an error. I made an compare of my solver and the reactingFoam solver (added pictures). You can see that the reactingFoam solver gives a better result due to the density of the different fluids and therefor you ll get other velocity values and other mixing values. So I thought building a solver which uses two fluids (constant/transportProperties or thermodynamics) with different physical properties it should be possible to be more accurate then the scalar solver. Is that right? How can I manage that? I dont wanna get a complete solution but some ideas what 's necessary would be very nice. Thanks tobi |
