Roshanlal New Member Roshan S Lal Join Date: Jul 2010 Posts: 5 Rep Power: 15	Hi friends I'm trying to model a supersonic reacting flow with crosswise injection of hydrogen gas at mach 1 into mach 2.5 main air stream. I'm using finite rate combustion model with the fluent 6.3 solver I want to find the combustion efficieny. And in the papers its given as ηc = 1 – [ ∫αρu dA / ∑m fuel in ] ; α = mass fraction of fuel How to evaluate this formula with fluent reports. Should I find the term ∫αρu dA by surface integral and flow rate with α as the variable. Is there any other means to get efficiency of combustion Plz help me......... Roshan
