<p>Hello, Neeraj,<\/p><p>If the flow is indeed turbulent, then the FR\/ED model is applicable. To numerically ignite the mixture, follow these steps:<\/p><\/p>\n

    \n
  1. run the calculation for some number of iterations, say, 100, to establish some mixing of the reactants.<\/li>\n
  2. define a small region in the expected flame region using, e.g., a region cell register, patch a high enough temperature (e.g., 2000 K) in this region. In addiiton, patch a reasonable value for a product species (e.g., co2 or h2o) mass fraction.<\/li>\n<\/ol>\n
