Hello foamers,

I am simulating a multiphase flow in a stirred tank using the solver multuphaseEulerFoam. And I want to calculate the forces and the moments applied on the impeller in order to calculate the torque.

Did someone have an idea about how to calculate these parameters?

Any help will be appreciated

Hi,

I'm a beginner user of OpenFOAM, so I'm not really sure what I'm telling you.
I had a similar problem. I run an incompressible steady-state case (simpleFoam) and I added, in the controlDict, the function in the attachment...

You will get a file with the three components (x,y,z) of force and moment at every time step.

Bye

Thank you for your response, well it is true, this script can be added, i worked with it using the solver simpleFoam. But for multiphase solvers, it doesn't work. & I don't know why..

No, unfortunately I didn't solve the problem.

If you find something, please share it with us.

Good luck!
