Numerical simulation of homogeneous turbulence submitted to plane strains and rotation
Abstract
Two fundamental mechanisms of three-dimensional turbulence, i.e., the return to isotropy following induced strain and the effect of rotation on spectral energy transfer, are investigated in order to understand the role of rotation when combined with plane strain. Return-to-isotropy simulations are performed with various anisotropic turbulent and initial fields. Results obtained in the rotation case for Rossby numbers from 0.01 to infinity are discussed.
