| Abstract | Fully developed rotating turbulent channel flow (RTCF) has been numerically investigated using large-eddy simulation (LES). The subgrid-scale (SGS) eddy viscosity model is base on an SGS helicity dissipation balance and the spectral relative helicity. Posterior test has been implemented to an RTCF with rotation in spanwise direction. The friction Reynolds number Re-tau = u(tau)delta / nu based on wall shear velocity u(tau) half width of the channel delta and the kinematic viscosity nu is 180. Two rotation numbers Ro(tau) =2 Omega delta / u(tau) equal to 22 and 80 have been computed with respective grid resolution. The results from dynamic Smagorinsky model (DSM) and direct numerical simulation (DNS) are used as references. The results demonstrate that the eddy viscosity model can predict both the precise velocity profile and the turbulent intensity. |
