Surface reaction in CFX!
 

In my model, there will be some surface reaction on one wall. SO I must define a third type of boundary condition. How to do this in CFX?

Thanks

You can define a massflux of the reactands at the wall. The rest of the reaction is to define in the >>MODEL DATA
:>CHEMISTRY section of the command file...

I hope this helps! Felix

but the mass flux is varies with the concentration on the wall, this can also be defined?

Thanks

CFX4 or CFX5?

Just define some source terms on your boundary. Shouldn't be very difficult.
