Abstract

Large eddy simulation of rotating channel and ribbed channel flows with and without heat transfer is reported. The rotation axis is parallel to the spanwise direction of the parallel plate channel. An implicit finite-volume scheme was used to solve the preconditioned time-dependent filtered Navier-Stokes equations using a dynamic subgrid-scale model to account for the subgrid-scale effects. The distribution of mean velocity and mean temperature were influenced by system rotation, transforming from a symmetric profile into a non-symmetric profile. The shift of peak values was toward the stable side of the channel. Near the stable (leading) side, the turbulent intensities and heat transfer were suppressed, but turbulence was enhanced with increasing shear stress and turbulent kinetic energy near the unstable (trailing) side.
