Scramjet Combustor Development: A Review
Abstract: In the development of scramjet engine, the combustor presents the most formidable problems. Combustor is the critical section due to practical constraints of suitable material, mixing and flame holding in the short span of length. The complex phenomenon of supersonic combustion involves turbulent mixing, shock interaction and heat release in supersonic flow. The flow field within the combustor of a scramjet engine is very complex and poses challenge in design …

Projections of Natural Absorption in Three-Dimensional Behind Phase into Turboprop Circulation
Abstract: Designed to enhance fuel-air mixing at supersonic speeds is one of the most difficult issues in the design of scramjet engine combustors. Various experiments and investigations were considered to boost fuel-air mixture in supersonic air streams. In this analysis, phase effects on transverse gaseous hydrogen injection into supersonic crossflow are examined numerically. Three-dimensional Reynolds Combined Navier-Stokes equations and k- sst turbulence model and perfect gas equation were numerically solved. Current …

Numerical Analysis of Oblique Impinge shock-wave/turbulent boundary-layer interaction Using Reynolds Average Navier Stroke Equations
Abstract: Interaction of shock waves with turbulent boundary layer plays an important role in the design and operability of high-speed aerospace vehicles and air-breathing engines. During interaction, the adverse pressure gradient of the shock is often strong enough to separate the boundary layer. Reynolds averaged Navier-Stokes simulations using conventional turbulence models do not predict the correct size and shape of the separation bubble in strong shock/turbulent boundary-layer interactions. The corresponding surface …
