A dynamic LES scheme for the vorticity transport equation: Formulation and a priori tests
This work aims at the development of a Lagrangian large eddy simulation (LES) scheme. The scheme is based on the filtered vorticity transport equation and on modeling the effects of subfilter scale (SEC) velocity and vorticity fluctuations using a dynamic eddy diffusivity model. The dynamic implementation of the model relies on multiple filtering in order to determine model coefficients from the resolved data. The performance of the dynamic SFS model is examined using a priori tests that are based on direct numerical simulations of forced, homogeneous, isotropic turbulence. \(\copyright\) Academic Press.
