Turbulence is a complex phenomenon that occurs in most engineering applications involving fluid dynamics. It is characterized by the irregular and chaotic motion of fluid particles, which can cause significant fluctuations in velocity and pressure. Until now, there has not been a single and practical turbulence model that can reliably predict all turbulent flows with sufficient accuracy. whereas many turbulence models have been developed from the perspective of finding different compromises between...

Here's the theory for relativeVelocityModel in OpenFOAM8 that I uncovered manually going through the code and commit history of OpenFOAM8.


Before we proceed, since there are a couple of main scientific schools in the world that use different notation, let me declare some notations that I'm going to be using:


<-- this dot is just a general sign for multiplication; both multiplication of scalars and scalar multiplication of vectors can be denoted...
