SDBD Enhanced Supercombustion Chamber Blending Characteristics Simulation Studies

In order to improve the fuel mixing efficiency of scramjet, combined with the research progress at home and abroad, the effect of surface dielectric barrier discharge plasma on the mixing of detached combustors was numerically simulated, and the impact of different positions and The results show that: positively excited plasma can increase fuel mixing length and reduce fuel penetration depth; and the effect of excitation forms on the fuel penetration depth and effect of blend length. The results show that: positively excited plasma can increase fuel mixing length and reduce fuel penetration depth; the effect of reversely excited plasma on fuel is related to the application position.
