Forced Homogeneous Isotropic Turbulence

ParsaT · February 22, 2021, 05:23

Dear All,

I was wondering if anyone is aware (or did it before) of how to implement a source term to the momentum equation to sustain the turbulence in a desired field by adding energy to the large-scale structures? For example, the turbulent kinetic energy of a Taylor-Green vortex decays after a certain period of time. I was wondering how to keep the turbulent kinetic energy sustain.

Regards,
