🍪 CFD cookie 2 - Visiting all RANS models in OpenFOAM - Laminar - Part 8

Описание: 👉 Turbulence models in OpenFOAM | Theory and numerical pointers 🤓
No turbulence model 😋
This is what people call DNS - All scales (kolmogorov slcales) are resolved in space and time. 🫡
DNS = Direct Numerical Simulation 🤯
Zero Pressure Gradient Flat Plate – Re = 10 000 000 👌

00:00 Introduction
01:10 Some remarks about DNS and the governing equations
02:26 Let's run the so called DNS simulation (under-resolved)
07:20 Residuals on-the-fly
08:09 Let's take a look at the solution
10:43 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?
