PREDICTION OF STREAMLINE CURVATURE EFFECTS ON WALL-BOUNDED TURBULENT FLOWS

Abstract

A low-Reynolds-number second-moment closure without wall-reflection redistribution terms is tested in wall-bounded turbulent flows with streamline curvature. The test cases are two fully-developed curved channel flows and four boundary layers on curved walls. The turbulence model captures main features of the stabilizing and destabilizing effects of streamline curvature, though some notable discrepancies between the predictions and measurements are present in boundary layers on convex walls.
