Help and Guidance required: Implementing Photochemistry in fluent
 

Hello,

I am trying to add photochemistry in my fluent model but I am not sure how to do it. In the model, a gas, let's say, 'A' flowing through a reactor should interact with photon (incident radiation) and reduce to products 'B' and 'C'. The reaction can be represented like: A + photons --> B + C
with reaction rate constant 'k'.

I think I may need a udf for it, but I am not sure how to write it and implement in fluent. Any help, guidance, suggestion or any literature relating to it is highly appreciated.

Best regards,
