Heatflux Calculation at Walls during Convective HT Analysis


#1

Hello everyone,

I would like to use the Convective Heat Transfer Simulation type to learn something about the Heat Transfer at Fluid-Solid walls. I know that I could use the Conjugated Heat Transfer Analysis, but it does not support imcompressible fluids yet (and the Boussinesq Approximation).

My Setup would be a fluid volume with some Isothermal hot surfaces and some cold ones. To calculate the Nussel Number I just need the Temperatur Gradient at the hot surface or the heat flux density.

Is it possible to calculate these values in the Post Processing (e.g. in Paraview) ?
Or is there another opportunity to calculate the Nusselt number?

Maybe someone can help me :wink:

Regards
Malte

Hi (again :wink: ) Malte!

I know that ‘wallheatflux’ inside OpenFOAM does that job but I am not sure how to this in Paraview, found this document: https://projekter.aau.dk/projekter/files/239502526/Report_UPLOAD_Version.pdf. Maybe the @CFD-SQUAD can help? :slight_smile:

Cheers!
