• GS40 Direct Numerical Simulation for Streamwise-Rotating Homogeneous Shear Turbulence with Several Shear Rate

抄録

In this study, the direct numerical simulation for homogeneous shear turbulence in the system rotating along the streamwise direction with three shear rates is performed. Owing to the rotation effect, the turbulence energy becomes small during the initial short time, and the anisotropy of the Reynolds normal stresses and that of the kinetic power spectra are strengthened. In the case of the strong shear rate, the small vortex structures are activated and stand in a line along the rotating axis.
