Equillibrium Reactions
 
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

sure let me know if its not too late

i got that dude .... facing some other problem related to volume reaction along with surface reaction .....

majid_esi January 17, 2012 04:59

and whats that?

sulabh gupta January 17, 2012 05:25

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 ...

majid_esi January 17, 2012 06:25

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?

sulabh gupta January 18, 2012 00:50

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 .
