RICHARDYW is on a distinguished road
Hello,
I'm a freshman in CFD and I want to model premixed combustion by using Large eddy simulation and in this case, 'premixed combustion model' is selected.

It's a 2D simulation and I don't know how to set up the equivalent ratio in 'material' selection step. Because I want the air and fuel homogeneously premixed at the inlet of the model.

the attachment shows the test result, this picture illustrates the progress variable (probably wrong), Because it is just a test so the quality of mesh is poor.

The ignition point is set at the begging, at the centre of the inlet.

Also, I want to generate the result of reaction rate but obviously I have no idea to achieve it.

I would be extremely grateful if anyone can help me.

Thank you very much

Richard
