DNS , LES , and wall - modeled LES of separating flow over periodic hills

Abstract

Separating flow in a channel with streamwise periodic constrictions is investigated using direct numerical simulation (DNS), large eddy simulation (LES), and wall-modeled LES (WMLES). The Reynolds number based on the hill height and the bulk velocity above the hill crest is 10,595. The results presented include mean velocities, Reynolds stresses, and… (More)
