forces on wall in twoPhaseEulerFoam

hannes · March 12, 2024, 13:48

Hello everyone!

I want to use twoPhaseEulerFoam to simulate the propagation of an air layer along a wall and evaluate the tangential force on the wall.
It looks like the common forces function object does not work here.
Does anyone have a hint on how to proceed with this evaluation?

Thanks!

Hey!

If you are interested mainly in tangential (viscous) forces, maybe you can use the wallShearStress FO and integrate this on the surface with Paraview?

Hello,
Computing the wallShearStress of a phase has been implemented in OpenFOAM v11.

https://cpp.openfoam.org/v11/wallShe...8H_source.html

You can take a look at this and see if it helps you to implement it for twoPhaseEulerFoam

Thanks

Do you have detailed instructions on using these tools?
