ABSTRACT	A computer code for the simulation of the turbulent reacting flow in a jet assisted ram combustor is developed.FAvre averaged Continuity and Navier-Stokes equations,equations for a low Reynolds number κ-ε model and equations for mixture fraction and its variance are solved to simulate the turbulant reacting flow.A Stretched Laminar Flamelet Model (SLFM) in the miprobability distribution function for the scalar dissipation.All other mass averaged thermo-chemical variables are computed off-line after a converged solution has been achieved.Solution of the continuity equiation and the three momentum equations is acieved using the SIMPLER algorithm.The linearised system of equations for each variable is solved sequantially using a Incomplete Lower Upper pre-conditioned conjugate gradient method.Simulation results shoeing the recirculation zones,distribution of species and temperature are presented.
