Hi to all,
As it is known that the root mean square of the turbulent velocity fluctuation can be calculated in RANS as follows (if the turbulent kinetic energy k is known );
u'=(2k/3)^0.5
I am doing simulation in OpenFOAM using one equation eddy viscosity model under the framework of impilicit LES and i want to calculated the rms of turbulent velocity for this LES model.
I would like to ask that is there any expression in LES like indicated in RANS to calculate it ?
Thank you.
