文摘
LES and RANS of wind-wave forced boundary layers in a shallow ocean are presented. Wind-wave forced turbulence is characterized by Langmuir circulation (LC). Wall modeling based on weak enforcement of BCs is developed for RANS. RANS wall model predicts accurate log-law disruption caused by LC. Near-wall modeling in LES facilitates simulations of LC with expanded domains.
