Advanced RANS and hybrid RANS/LES turbulence modelling in CFD

10 key concepts everyone must understand in CFD / By

There is a big gap between classical RANS turbulence modelling and scale-resolving approaches like LES and DNS, both in terms of computational cost and what can be resolved. As a result, classical RANS modelling may be cheap but not always able to resolve the physics we want to capture, while LES and DNS may be …

In today’s article, we will be finally looking at the pinnacle of CFD: Reynolds-averaged Navier-Stokes (RANS) turbulence modelling. If you have ever wondered not just what RANS is, but also how it works under the hood, then this article is for you. RANS turbulence modelling is so instrumental that no one can really claim to …
