Reynolds stress anisotropy and secondary flow prediction in turbulent channel flow over riblets: A comparison of large-eddy simulation with linear and nonlinear Reynolds-averaged Navier–Stokes closures
Near-wall Reynolds stress anisotropy and secondary flows play a dominant role in drag reduction over riblets. In this study, a systematic evaluation of the wall-adapting local eddy-viscosity model, the shear-stress transport (SST) k–ω model, and the Wallin–Johansson explicit algebraic Reynolds stress model (WJ-BSL-EARS...
