Open publisher page 5 citations

Abstract

Homogeneous isotropic turbulence in the presence of rotation has been numerically investigated by the MRT-lattice Boltzmann equations with a forcing term. The influence of rotation on the turbulence is studied in detail. In particular, we examine turbulence energy, dissipation rate, the Kolmogorov length, and integral length. Three-dimensional iso-surfaces for the vorticity magnitude and velocity magnitude are also generated. Furthermore, two- and three-dimensional vorticity contours are presented to further demonstrate rotational effects on turbulence. Finally, we study the effects of wave number on the rotating turbulence.
