Chemkin-Pro – SI Zonal Model – Residual EGR

    • p.brosnan


      I am using the HCCI and SI zonal models to simulate Ethanol and Hydrogen combustion in an ICE. I would like to add a percentage of residual exhaust gas (in this case, 48%) to my model. Do I need to add the fraction of the residual exhaust CO2 in the "Add Species" tab?

      Thanks in advance,

      If Exhaust gas is recirculating back from the end of a process, I don't think you have to specify its makeup.  This is generally a function of the solution.
