Need mass fraction from individual reaction in multi-step chemistry combustion

    • me20s045

      I am trying to simulate a Laminar diffusion flame using a multi-step chemical mechanism. For post-processing, I need to know the mass fraction of a compound formed from multiple reactions.

      I am using a "stiff chemistry solver".


      For example ;

      Reaction 1: A1+B1=C1+D1

      Reaction 2: A2+B2=C1+D2

      Reaction 3: A3+B3=C1+D3


      So, what is the mass fraction of C1 produced in Reaction 1,2 and 3 respectively? I am currently not able to find a way.

      The solver will track species creation, but not sure it'll tag which reaction created it. However, as you know the production rate of D1, D2 & D3 I suspect you can work it out.
