I'm trying to simulate the mixture of Air and Methane in a combustion chamber. How can I get the distribution of Phi (Equivalence ratio)?

Hello Mahbub,
Try PROSTAR's operate command. If your methane fuel is scalar #1 and any residual gases are scalar #2, you could use: *set,afst,17.20105 ! stoichiometric A/F ratio oper,getc,conc,5,1 $oper,getc,conc,6,2 oper,add,5,6,4 $oper,ssub,1,4,4 $oper,divi,4,5,4 oper,sdiv,afst,4,4 Best regards, Lars Ola |

Hi Lars, Thanks a lot. Would you please tell me the unit of that scalar concentration?

Hello Mahbub,
I'm personally using SI units but the equivalence ratio is anyway a dimensionless quantity. The inputs are the scalar mass fractions as obtained directly from STAR-CD and the stoichiometric air/fuel (mass) ratio, which is also dimensionless. Regs. Lars Ola |
