• Visualization of Internal Flowfield in Two-dimensional Supersonic Ejector Nozzles

抄録

One of the most promising exhaust nozzles for a future super/hypersonic transport will be a non-axisymmetric variable geometry nozzle and more than likely the ejector nozzle which introduces bleed/bypass air from the intake section to solve inlet/engine flow mismatch, cool nozzle walls, reduce external drags, and then improve overall performance of the propulsion system. In the present study, scale model tests with a typical 2D-CD ejector nozzle have been carried out to investigate the internal flowfield using optical flow visualization techniques. A specially designed Mach-Zehnder interferometer has been used to get equi-density interferograms for internal flow near the throat region. A multicolor schlieren method has been also used to demonstrate shear layers and waves. A CFD prediction has been carried out and compared with the test result.
