Abstract
The flow field of a ramp cavity based scramjet combustor with kerosene fuel is explored numerically using commercial CFD software. Three-dimensional Navier-Stokes equations are solved alongwith K - e turbulence model and fast rate chemical kinetics. Liquid kerosene is considered as disperse phase fluid and is modeled through Lagrangian tracking method. Simulation captures all essential features of the flow field. Good agreement between computational and experimental values forms the basis of further analysis. The flow phenomena in the combustor are presented through the distribution of important thermochemical parameters at different cross sections. Normal shock is seen to occur in the combustor and significant upstream interaction was observed due to heat release. The computed combustion efficiency is near unity as the fuel equivalence ratio is small.
