Julie Polyakh Guest Posts: n/a	Hi! I'm trying to simulate the counterflow combustion. The flow is laminar incompressible (max velocity = 1.2 m/s); CHKI reaction scheme is used; the fuel is Heptane (gas). The fuel and oxidizer contact zone and attached area is chosen as ignition region; Fuel fraction = 0.1; ignition iteration number is 50; ignition temperature = 1700 K. Applying the scheme I obtain the temperature rise about 200 K at the region where the fuel concentration is zero (?!!!). That's it. Does someone know where my mistake is? Thanks in advance, Julie
