InterFoam vs lesInterFoam

in_flu_ence · October 28, 2007, 19:34

Hi,

1) Is interFoam meant only for laminar flow and does not account for any turbulence that occur?

2) If (1) is true, is there any guided tutorial on the lesInterFoam solver? I have tried to figure out the files in the nozzle2D folder but I have no clue.

Thanks very much

Yes interFoam is only for laminar flow. rasInterFoam does have turbulence modeling.

i do not think there is a tuorial for lesinterfoam solver

Thanks Kumar.

I have read somewhere in the forum that ras with VOF will actually compromise on the sharpness of the interface and LES is a better option to go with.

However, I don't quite know the different parameters that I have to key in. Do you have a chance to know about them?

Thanks
