Dynamic subgrid scale modeling of turbulent flows using lattice-Boltzmann method

Premnath, Kannan N.; Pattison, Martin J.; Banerjee, Sanjoy - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 13, pp. 2640-2658

In this paper, we discuss the incorporation of dynamic subgrid scale (SGS) models in the lattice-Boltzmann method (LBM) for large-eddy simulation (LES) of turbulent flows. The use of a dynamic procedure, which involves sampling or test-filtering of super-grid turbulence dynamics and subsequent...
