🍪 CFD cookie 2 - More on turbulence modeling - SSG Reynolds Stress Model - Part 26

👉 Turbulence models in OpenFOAM | Theory and numerical pointers 🤤
RANS simulation using the SSG Reynolds Stress Model (RSM) Turbulence model 😶‍🌫️
This is an anisotropic model 🤯
Zero Pressure Gradient Flat Plate – Re = 10 000 000 👌
00:00 Introduction
01:53 Let's take a look at the source code in OpenFOAM - Theory review
04:30 Let's visit the case in OpenFOAM
09:25 Literature review of the SSG RSM model
11:42 Let's run the simulation
14:12 Let's study the outcome of the simulation - Sensitivity to initial conditions
21:51 Let's compare different case configurations - Effect of wall reflection correction
22:57 Final remarks
This CFD cookie 🍪 is based on OpenFOAM 12, but the general guidelines and standard practices should work with any OpenFOAM version.

🤔 We also address the following question (CFD cookie 1):
Without reference results (experimental, analytical, etc.), how do I know that my turbulent Multiphysics simulations are correct?
