Hi,
I am new to Fluent and i want to simulate Constant Volume (BOMB) Combustion of a Fuel-air mixture.
There is no inlet, no outlet. Just a contant volume chamber filled with fuel-air mixture and then there is ignition at one of the walls. As the flame propagates the charge is converted to burned gas and eventually the flame extinguishes. I want to study the heat flux to the walls due to this combustion.
I was trying to use CHEMKIN-CFD module in Fluent, but i am really struggling to set up the problem.
Can any body help me here please. Is CHEMKIN-CFD the right module for this kind of problem.
thanks,
Iltesham.

Hi,
That is interesting. First, how do you combine the CHEMKIN and FLUENT?
As I see, it is not easy to couple CHEMKIN mechanism with Fluent.

There is a module in Fluent 12.1 called "CHEMKIN-CFD" it solves both flow equations and chemical kinetic equations.

Have you tried the 'spark model' ?
