Hi everyone
I have just started using CFD ACE. I have a small query regarding how to set a equillibrium reaction in CFD ACE.
Thank you

If you have to solve for both reactions taking place in the volume of the reactor and one reaction on the surface of the reactor than how to proceed ...

well, you can define the surface reaction on the boundary condition under chemical rex tab and volume reaction can be defined in volume condition again in chemical reaction tab

i knw that but the solution is not converged ....the reaction happens in some fractions of the reactor volume...

Is it Instantaneous reaction problem?

No you have a reaction rate constant .... we can also take equilibrium reaction rate constant....

Its is difficult to answer this query without looking into the problem.

The problem is I am simulating a Chemical Vapor Deposition Reactor for production of silicon. The reactor configuration is such that you have an U shape rod where deposition takes place .Its basically Seimens process for production of Silicon.
the surface reaction is
SIHCL3+H2->SI(B)+3HCL
along with this there are several volume reactions one of which is
SIHCL3->HCL+SICL2
how to proceed in this case .
Ty
