Simulate Wall adsorption/desorption of gaseous compounds on wall
 

Hi Guys,

I need to simulate adsorption/desorption phenomenon of gaseous compounds on wall.I need to capture this phenomenon on basis of langmuir's model that need to implement in UDF in Fluent.

Could you please give me suggestion that hows should I implement UDF for that and where to hook this UDF.

Please if somebody have idea,let me know.Thanks:)
