“…Both twodimensional [12][13][14] and three-dimensional [15][16][17][18] Navier Stokes simulations were reported. Most of the early calculations 15,16 were performed using MacCormack method and BaldwinLomax turbulence model to obtain global quantities of engineering interest rather than details of the flow field.…”

Staged transverse sonic injection into supersonic flow in a confined environment usually employed in scramjet combustor has been explored numerically using an indigenously developed three-dimensional Reynolds Averaged Navier Stokes solver with Roes scheme and k-w turbulence model. Simulations were carried out for both without injection and with injection in Mach 2 flow behind a backward-facing step in a rectangular duct. Simulation captured all finer details of flow structures including recirculation bubble behind a backward-facing step, barrel shocks and Mach discs caused due to transverse injection and reattachment of shear layer in the downstream wake region. K-w turbulence model with compressibility correction performed extremely well in predicting the overall behaviour of the flow field. The jet from the second injector was found to penetrate more in the free-stream due to the loss of free-stream total pressure across the barrel shock of the first injection point. Excellent agreement of computed profiles of various flow parameters at different axial locations in the duct with experimental results and other numerical results available in the literature demonstrate the robustness and accuracy of the indigenously developed code.

“…Therefore the investigators studied some physical phenomena or proposed the numerical method which are important for solution of the problem of the combustion. For example, this problem has been modeled by Drummond and Weidner [1][2] during that process Reynolds-averaged multispecies Navier-Stokes equations which were coupled with Baldwin-Lomax turbulence model have been solved by using the explicit predictor-corrector scheme of MacCormack. Drummond and Weidner modeled injection of fuel from two slots and studied influence of the slots width on the process of mixing.…”

“…Mathematical models have been successfully realized for flow of perfect gases [1][2][3][4], but the practical design of supersonic ramjet (scramjet) engines requires an understanding of jet interaction with a crossflow for multispecies gases. The flow field in such devices is complicated by geometrical factors, turbulent fuel-air mixing, chemical reaction, shock waves, and separation regions ahead of and behind the jet.…”

“…Development on the code continued into the early 1980s when the code was used to carry out the first simulation of a scramjet flowfield using a 2-D model of an engine module [27]. Detailed studies to optimize the configuration of scramjet fuel injectors were also completed during this period [28,29].…”
