| Abstract: | ith a high speed camera and schlieren optical system, dynamic and static pressuretransducers, temperature sensors, auto-ignition and non-steady processes in supersonic air flow with injecting transversely hydrogen are studied by tests. Wall pressures changing with time within auto-ignition processes in recirculating zone downstream the injector, and wall pressures rises in axial direction are measured. Effects of the airstream's total temperature and the amount of injecting hydrogenon auto-ignition processes are considered. |
