Abstract

This paper describes the main results of direct simulation and large eddy simulation of homogeneous turbulence submitted to two kinds of constant mean velocity gradients. The Taylor microscale Reynolds number is in the range 20–70. The two strains considered are plane strain and solid body rotation. For the plane strain case, the two described simulations show clearly the reorganizing processes of the turbulent field after each abrupt change of the imposed strain. For the rotation case, three different effects of the rotation are enhanced by a judicious choice of appropriate initial turbulent (isotropic and anisotropic) or random initial conditions.
