LES in twoPhaseEulerFoam
 
dear foamer

if i have correct understanding, twoPhaseEulerFoam can use LES turbulence model ? is it true?

if yes, how can i use it in simulation of fluidized bed?

regards,

LES need to included
 
I think the default turbulence model is kEpsilon model.

if you need to use LES in twoPhaseEulerFoam, then you may need to modify the code a little bit.

thanks Charlie

what is the meaning of the filterProperties file in its case??

filterProperties
 
According to a tutorial, the function is set the flux to be 0 at the filter position and specified plane.

I don't think it does anything... i cant find any reference to filter in the code at all...?

Could I kindly ask you which filter type is used in LES of incompressible flows OpenFoam? In fact, we don't set any filter in LESproprties.
