An axisymmetric Navier-Stokes code was developed to analyze mixing flow in a duct for a turbo-ramjet engine. The three-step Runge-Kutta scheme is used to drive the solution toward a steady state. The Lam-Bremhorst low-Reynolds number k-epsilon model was used to simulate the effect of turbulence on mixing phenomenon. An experiment using a scaled model duct was conducted to validate the numerical code. The predictions of mixing, mass flow and unsteady pressure fluctuation are mainly compared with the experimental data because they are key issues for the design of the duct. Comparison with experimental data indicated that computed results successfully captured important features of mixing flow phenomenon for steady state.
