Hi,
I am trying to write a mass transfer udf. to calculate mass transfer, i need contact area between liquid and air. would you please help me how can I find the contact area in udf which is the height of cell (2d) ? Thanks, |

Do you want to extract the mass transfer from your simulation, or prescribe the mass transfer in your simulation?
If it is the first: you might not need to know the contact area, think of conservation of mass... If it is the second: then you need to define the contact area in your geometry.

S = Kg*(Wgb-Wge)*A Which A is contact area. I am calculating this value for each cell, since the cell size is growing from inlet, I am looking for a way to calculate cell height for each cell? |
