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

Tags compilation, openfoam

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.

Updated September 22, 2018 at 12:52 by student666

Tags internal faces, openfoam, pre processing

Objective: test cases for using following dicts:

createPatchDict
createBafflesDict

Preliminary steps:

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

Tags dpmfoam, lognormal, mppic, openfoam

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...
