Unified turbulence models for LES and RANS, FDF and PDF simulations

A review of existing basic turbulence modeling approaches reveals the need for the development of unified turbulence models which can be used continuously as filter density function (FDF) or probability density function (PDF) methods, large eddy simulation (LES) or Reynolds-averaged Navier–Stokes (RANS) methods. It is then shown that such unified stochastic and deterministic turbulence models c...

Microscales of turbulence and heat transfer correlations

The small-scale structure of forced, turbulent flows developed after Taylor and Kolmogorov is extended to that of buoyancy-driven flows. A thermal microscale

An extensive study on LES, RANS and hybrid RANS/LES simulation of a narrow-gap open Taylor-Couette flow

The present paper concerns a numerical benchmark of various turbulence modelings, from RANS to LES, applied to Taylor-Couette-Poiseuille flows in a narrow gap cavity for six different combinations of rotational and axial Reynolds numbers. Two sets of refined Large-Eddy Simulation results, using the WALE and the Dynamic Smagorinsky subgrid scale models available within an in-house code based on ...
