Hi everyone,
I am trying to model boundary layer turbulent combustion with a global step mechanism i.e
C4H6 + 5.5O2 ---> 4CO2 + 3H2O
I am following Finite rate/ Eddy Dissipation model but I am confused what to substitute in rate exponent for the above global one step reaction as I don't have molar concentration data with various time intervals.
Secondly, as I am using single phase gaseous combustion mechanism, how can I patch the fuel at higher temperature or have to use Multiphase option to patch the fuel near the wall so that I can find Heat transfer to wall as well..??
Kindly help me...
Thanx in advance to all..
