Abstract
A near-wall eddy-viscosity formulation for LES is presented. This formulation consists of imposing a RANS eddy-viscosity dynamically corrected with the resolved turbulent stress in the near-wall region. The RANS eddy-viscosity is obtained from an averaged velocity profile of a resolved LES of channel flow at Reτ = 395 and stored in a look-up table. Results are presented for channel flow at Reτ = 395 with no-slip boundary conditions, and up to Reτ = 1, 000, 000 using a wall model.
