Default multiple reactions
Posts: n/a
hi, is there any way i can use two different turbulence chemistry interactions for different reactions in fluent. i got two reactions in my reactor and i want to use laminar finite rate for one and eddy dissipation for other. thanks in advance. siva

There might be several approach. The easiest way is :

You can do it by choosing combined model and by controlling reaction parameters.

For example, If you want to use eddy dissipation model, use reasonable eddy dissipation model parameters and very very small activation energy(or very very large pre-exponential constant). Then, chemical kinetics is very very fast, so that eddy dissipation model, which is slower reaction, can only be used. Vice versa.

Recall that slower reaction is used for combined model.

Sincerely, Jinwook
