Turbulence Model L.E.S
 

Good Moning Everybody,

Please if every one can answer me, i am doing a simulation in 2D
Can i use L.E.S as a turbulence Model in 2D simulation
because L.E.S turbulence model is very robust

Thank you in advance

Hi,

You cannot run LES in 2D. LES requires at least part of the turbulence energy cascade to be modelled and this is an inherently 3D process, even in a 2D geometry. If you want to run in 2D you need a RANS turbulence model.
