Abstract: In this paper, reacting flows in an aero-engine afterburner are analyzed using computational fluid dynamics (CFD). A computational procedure is described for calculating the three-dimensional reacting flow fields in a gas turbine afterburner. The computations are based on numerical solution of time-averaged transport equations for mass, momentum, turbulent kinetic energy and dissipation rate using a finite volume formulation. The numerical calculations are performed using SIMPLE(Semi Implicit Method for Pressure Linked Equations). The RNG (Re-normalization Group Theory) k-ɛ model is used for turbulence modeling. Combustion is modeled using PDF (Probability Density Function). The results for air-fuel Ratio of 30 and 46 are obtained and analyzed.
