A numerical study of alternate scramjet fuel injectors using tiem-marching and space-marching navier stokes methods

摘要

A numerical study comparing a set of related scramjet fuel injectors has been performed. The injectors are all based upon the swept ramp configuration studied experimentally at the University of Virginia. A parametric study was performed in which the shape and location of the injectors on the back face of the ramp was varied, while keeping the injectant mass flow constant. The effect on mixing efficiency was monitored.
