it's ok, I understand. well, I'm just gonna send you some pictures so you can understand my geometry and what I'm trying to do.

first of all, here is my geometry:

this is a drying chamber made of wood with 2 trays as a porous media. air is heated at the bottom by

the mean of a horizontal absorber which is considered as a source of energy

The air flows into the dryer through an inlet, absorbs energy (heat) from the absorber (Aluminum), flows

through the drying chamber and outflows from the outlet.

`trays were assumed as porous media for airflow. It is modeled by the power law model using C0 and C1.`

`boundary conditions in the inlet: P= 100000 Pa  and  T=304 K`

`boundary conditions in the outlet: P= 100000 Pa`

`Wooden wall boundary conditions: u=v=0`

`there is convective loss in all the walls and in the absorber,`

`the standard k-? model is used to describe the flow.`

I know it's a lot but please be patient with me, and again I'm so grateful for keeping answering me

Best regards,

Dounia
