Turbulence modeling is an essential element of any computational fluid dynamics (CFD) simulation of practical industrial problems. However, the selection of the most appropriate model is not a trivial task.
In this webinar, we will be looking at a number of fundamental aspects of turbulence modeling and how they affect the solution. We will make the distinction between statistical (essentially RANS models) and scale-resolving simulations (LES, DES). We will be presenting the most important aspects of the wall-treatment - with and without roughness - and will address the main elements of the transition models.
The influence of the turbulence models will be illustrated on several examples, using canonical cases (channel flow, boundary layers), and on cases directly related to the marine industry.
