Anisotropic turbulence model

mecbe2002 · November 27, 2014, 06:54

Hi,

I am looking for Explicit algebraic stress model to capture the anistropy in the turbulence for compressible flows.

I want to estimate the noise in the exhaust plume of the solid rocket. In on the paper they used RANS turbulence model which can capture anisotropy in the turbulence.

I checked the available model in openfoam but couldn't find one. So is it available or not?

Thanks
KGN

What about a Reynolds Stress Model? There is at least on available for compressible flows.

Thanks. I will look into it.

Even though the nozzle is axi-symmetric, i have to do full 3D simulation to capture the anisotropic turbulence in the flow. Am i correct.
