Abstract
Two models, an algebraic WMLES and IDDES, were tested on their ability to predict wall-bounded flows with pressure gradient. A developed flow between two moving flat plates under an adjusted pressure gradient (Couette-Poiseulle flow) was used for testing. Within two considered test cases three types of boundary layers were examined: boundary layer with adverse pressure gradient (APG), boundary layer with favorable pressure gradient (FPG) and a wall-bounded flow with negligible skin-friction. It was shown that both models are capable of accurate prediction of the flow structure and mean parameters of boundary layers with APG and FPG and of frictionless wall-bounded flow. The difference between simulation results and DNS data is less than 7%.
