Stack effect test

i am trying to test stack effect and the effect of opens shape 

body to the right is static air in the meddle solid material has opens , to the left 

there is a a forced air, i expected that the air will flow from right to to the left volume 

under the pressure and temperature difference between right and left volumes.

unfortunately, air flows from left to the   right, 

could you please check the model, the material properties, and the boundary condition 

and if there is any way to make this thing happen

actually it works, 

but still need to know it there is any concern about volumes sizes

Hi @eng.abass5,

 

Glad to see the air is flowing in the expected flow direction. The results look good- lots of upstream/downstream entrance length, the results look mesh independent, and the results/gradients seem fully converged. Nicely done. 

 

 

Thanks,
