Species transport combustion model

hari

Dear mate,

I have to simulate with 2 velocity inlets with different materials in my simulation. 1 is air and another one is propylene-air mixture. If I use species transport model for propylene-air mixture how to initialize and if I initialize the higher velocity of air inlet does the propylene-air mixture will take automatically from the another inlet. I think I should go for injection option for propylene-air mixture

Bit confused ..how to do Can anyone explain Thanks in advance
