Influences of Geometric Parameters upon Nozzle Performances in Scramjets

This article investigates and presents the influences of geomea'ic parameters of a scramjet exerting upon its nozzle performances. These parameters include divergent angles, total lengths, height ratios, cowl lengths, and cowl angles. The flow field within the scramjet nozzle is simulated numerically by using the CFD software--FLUENT in association with coupled implicit solver and an RNG k-ε tur-bulence model.
