Abstract: In Reynolds stress models (RSM), the use of first gradient closures to model diffusion fluxes may lead to a nonconvergence with mesh refinement, especially if the flow experiences episodes of dominant compressibility effects ...

Abstract: In this paper, we propose a kind of buoyancydriven flow leading to unstably stratified homogeneous (USH) turbulence. This approach is developed in the context of incompressible Navier–Stokes equations under Boussinesq ...
