probleme with mass conservation
hi, every one
My problem is a two-dimensional double diffusion problemin square cavity. there is a temperature difference and a concentration difference between vertical walls, and the horizontal wall is adiabatic and impermeable.
i tried to simulate my problem:
- i checked the report flux for the total mass rate i`am surprised because it displayed zero on vertical walls while i imposed mass fraction !!!
i calculated the sherwood number for the right and left walls and i didn`t had a conservation
for the mixture i used(air+h2o vapor) with imposed physical properties
