piloted turbulent spray flame
Hi everyone,

I m setting a simulation of a piloted spray flame combustion, in Fluent 14, with the non premixed combustion model. Spray fuel, so using droplets injection and PDF-mixture material, and air must be assigned from the same inlet. This flame will be ignited by a exhaust gas surrounding, with a specific composition, which has a different inlet in the domain. From a third anulus, there is a stream of coflow air, which shouldn t be a problem to model. How can I assign the inlet boundary conditions for fuel-air, same inlet, and pilot gas? Has the pilot gas to be simulated as a second stream?It s not fuel tho! I am a bit confused, as I cannot even specify the material when going through the BC.
hope I ve been clear
