Simulate a cylindrical combustor burning methane CH4 in air using the finiterate chemistry model

zou_mo · January 12, 2006, 02:39

Which solver in OpenFOAM1.2 can be used to simulate this problem? I am not a expert for combustion.

Thanks all.

Hi Zou!
OpenFOAM has two solvers for turbulent combustion:

- XiFoam: solver for turbulent premixed combustion with the Weller model (known also as b-Xi)

- ReactingFoam: solver for turbulent combustion with the Partially Stirred Reactor Model and complex chemistry. The partially stirred reactor is a modified version of the EDC model by Magnussen.

If you want to use the finite rate chemistry model you have to implement it by yourself. Before implementing that, study in detail the two applications I previously mentioned.

Also have a look at the classes contained in

$FOAM_SRC/thermophysicalModels/combustion

$FOAM_SRC/thermophysicalModels/chemistryModel

Regards.

Thank you.
Now I want to simulate the turbulent combustion in the SCRAMJET combustor shown below:

.
The air and fuel are injected into the field from different positions.

In OpenFOAM, which solver can be used to to this? ReactingFoam or other?

Thanks.

My own CFD code failed to give nice result for the problem mentioned above. If possible, I want to solve it with OpenFOAM.
