Hello,
While reviewing results on the boundaries of my mesh, there is a "dimensionless_heat_flux" component. I could not find what its definition was in the documentation. Can anyone enlighten me?
Best regards
Dimensionless heat flux

Re: Dimensionless heat flux
Hello,
If I remember correctly, this is an attempt at the estimation of the Nusselt Number. But contrary to the "real" Nusselt number which is based on a bulk temperature in a zone which needs to be chosen, this uses the near wall temperature (i.e. the temperare in the cell adjacent to a boundary face) as the bulk. So it may be sensitive to mesh refinement in the near wall region...
Best regards,
