Computational Fluid Dynamics Strut Flame Holder Efficiency ffor Supersonic Combustion

Main Article Content



For hypersonic vehicles, the ramjet engine's supersonic burning process is considered a suitable propulsion technology. The
flow in the combustor has an extremely short residence time (milliseconds) due to the supersonic combustion. Fuel-air mixing and
combustion efficiency have been evaluated using both normal and tangential fuel injection.. Shocks and vorticity created in the combustor
keep the flame in place and prolong its stay in there. For CFD analysis, the commercial numerical programme ANSYS FLUENT 15 i s
used. ICEM CFD is used for geometry and meshing, whereas FLUENT is used for analysis. Simulated flow field of hydrogen-fueled
scramjet combustor has been used to the finite-rate/eddy-dissipation reaction model. Fuel injector count is being investigated at different
Combustor inlets with a Mach number of 2.0 and fuel being introduced under sonic circumstances. Combustion efficiency is measured as
a function of the total mass of H2O in the combustor. Aiming for a better fuel-air combination in the combustion chamber and achieving
optimum combustion efficiency were the main goals of the work done.
