Hey all,

I am working on a partially premixed flame burner.I have a problem in defining the species. I have 2 inlets, 1st inlet has Nitrogen, 2nd is acetylene and air. The flame is in an air environment. When I choose partially premixed combustion model I have only two options, fuel and oxidizer, so in the fuel I mention the mole fraction of acetylene and oxygen and nitrogen and in the oxidizer only Nitrogen for the one of the inlet but now because of that I cannot specify air as my fluid surface. How can I supply an additional stream? in this mode of the model.

Any help is appreciated. Thanks!

hi, in your case, you must chose partially-premixed

Dear sir

i am trying to ignite the mixture by compression stroke 30ms , to attain high temp near 770K, using the chemkin file and dynamic mesh.

But i am not seeing the temperature rise in compression stroke.

Pl suggest what is wrong
