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.

Compilation of OpenFOAM v1912 with runTimePostProcessing

Posted July 17, 2020 at 07:08 by snak

runTimePostProcessing functionality is not available in precompiled packages of v1912.

I will note how to compile OFv1912 with runTimePostProcessing.

Code:
cd $WM_THIRD_PARTY_DIR
makeParaView
check the VTK version with the following command.

Code:
cat ParaView-v5.6.3/VTK/CMake/vtkVersion.cmake
If the version is 8.2.0, create a link with the name of VTK-8.2.0.

Code:
ln -s ParaView-v5.6.3/VTK/ VTK-8.2.0
Now, compile the VTK.

Baffles01 - createPatch & createBaffle

Posted July 21, 2018 at 11:48 by student666
Updated September 22, 2018 at 12:52 by student666

Objective: test cases for using following dicts:
  • createPatchDict
  • createBafflesDict

Preliminary steps:
  1. Run the Salome script for the geometry and surface mesh generation
  2. Export walls, inlet outlet inside cad/stl as STL (ASCII)
  3. Run the utility buildRegionSTL, it will create the constant/triSurface folder with buildRegionSTL.stl
  4. Export the interna mesh as interna.stl inside constant/triSurface

************Set up the SHM dict file for create Patch (highlights)...

Lognormal Distribution for Particle Size in OpenFOAM

Posted May 1, 2018 at 11:13 by Mehar

This is for future reference, if anyone wants to use lognormal particle distribution in OpenFoam.
1) Generate PDF from following formula


Here mu and sigma are the geometric mean and standard deviation of the particle size distribution
Here is an example plot of the lognormal distribution with mean 1 and standard deviations of 1.8, and 3. You can first re-create lognormal distribution with these parameters...
