fluent problem on combustion
 
friends... i am doing simulation of "combustion of methane air in diverging micro channel" but I am not getting appropriate result. Even I am not getting flame. sometime I am facing floating problem and non positive volume problem...so pls help me that how can I solve this problem..by using fluent. and also tell me that what boundary condition i must use and use of model to solve it....is this problem relate to laminar or turbulent.??

dear mohitmmb
 
read Tutorial 12. Cold Flow Simulation Inside an SI Engine of Ansys Tutorial.
I think it will help you

hi...., I read the cold flow problem.... but problem is littile bit different. I am doing simulation of combustion of ch4+ air(its species) in a divergent channel but i dont know the value of mass fravtion of ch4 and air species at inlet and outlet for a perticular equivalance ratio.....means suppose for equivalance ratio = 1 or 1.2
what will be the value of ch4, co2, c, o2, n2, h2o, etc at inlet and outlet...that is why I am not getting the exact flame and results....pls help me if possible....
