Liquid propellant combustion waves
Abstract
Design of efficient and stable combustors depends on accurate analysis of flowfields. This study examines combustion waves arising from hydrogen-air reactions in the scramjet flame holders with various ramp angles. Two-step Taylor-Galerkin finite element methods are used to solve the Navier-Stokes system of equations. Fluctuation quantities are calculated from the Navier-Stokes solution as a function of time. From these data the energy growth rate parameters and energy growth factors using the entropy-controlled instability method are determined.
