Turbulence modeling

Theory

  • In this tutorial you find the basic theory of turbulence modeling.
  • This tutorial gives a compact explanation of a laminar solver as well as a turbulent solver and the difference between them.
  • Here you will find a basic 2D hands-on tutorial to understand the theory of steady-state turbulence modeling.
  • Here you will find a basic 2D hands-on tutorial to understand the theory of transient turbulence modeling.

Application cases

  • This tutorial describes the flow over a rearward facing step in detail.
  • Here you will learn about the flow around a car.
