I do some research with CFX to simulate the natural gas combustion. I would like to combine detailed NOx model with the K-e model. Who could give me some advice about this. Thanks in advance.

Normally, you can implement your reactions in the COMMAND file but the number of reactions are limited. Since you intend to have a detailed mechanism, I think you should get in touch with their customer support. If you are going to change your reaction rates, you should use USRRAC or USRRAT. I think in the first step, you should try defining your problem and contact CFX customer support.
