How to install unbuntu system and open foam in your computer by VM


First，you should go to this site: https://cn.ubuntu.com/download. In this site ,you can install this package. The package's name is ubuntu-22.04.1-desktop-amd64 (1).iso . it's type is iso. After you download it, you should reserve it instead of releasing it. Then, you should install a software named Vmware Work Staion. Last, you should download openfoam and thirdParty. When you finish the installation...

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...

Recently I've been running a simulation of a Ranque Hilsch Vortex Tube in OpenFOAM. This went well for a time but when I tried refining and implementing a new mesh, it all came crashing down, showing negative total temperatures with gradients of more than 600 K for neighbouring cells. Since my experience with OpenFOAM is still rather limited, I tried with refining every surface up to a ridiculously high degree. After that mishap I went into it with my head on straight and started looking at what...

Hello Engineers and Scientists,

Preamble:
(If this is your first time then you may like read it, or you can skip it if it’s not your first time)

Being involved in CFD engineering and development/programming, I decided to dedicate some of the learning to community by writing through blog towards new budding CFD developers and engineers. So that new people don’t have to start from scratch. In this blog series, I shall try to create link to connect my files over...

Turbomachinery Solver OpenFOAM


This forum has been a big source of information for me since I started doing CFD. Now, I want to share my work to thank your altruistic knowledge sharing. Regarding the main topic of this blog, I am going to talk about my first turbomachinery simulations with rhoSimpleFoam, the problems I found with this solver and my solution, which I called turboSimpleFoam. Feel free to ask me whatever you want or tell me if something is wrong.
