Аннотация:A description of two methods for simulation of the flow around complex test configurations is considered. One method implements a well-known approach to solving the Reynolds-averaged Navier-Stokes equations with a closing differential turbulence model. Another method is based on scale-resolving wall-modelled LES approach (WMLES). The classical problem of the flow around the inclined backward-facing step with the generation of expansion waves, intensive shock waves and separated flow zones is considered. A comparison of computational and experimental data is done. The physics of the flow is described. The accuracy of the both approaches is evaluated.
