Also "The effective thermal conductivity in the porous medium is computed by FLUENT as the volume average of the fluid conductivity and the solid conductivity" vittal likes this.

hello
i am modelling porous media using discrete phase model.
I am unable to calculate permeability
I know velocity 5.6 m/s
pressure 5600pa
thickness of porous medium 0.15mm
droplet diameter 0.5 mm
