摘要

The colored-grid background oriented schlieren (CGBOS) technique is applied to the measurement of the interaction field of lateral jet and cross-flow. The test model is designed based on DLR's generic model. Experiments were carried out in supersonic blow-down wind tunnel of JAXA/ISAS with 0.6 m × 0.6 m test section. Free-stream Mach number is set to 2.0. The quantitative experimental data obtained by CGBOS technique and the reconstruction results of the density for the interaction field between cross-flow and lateral jet are described. Unsteady phenomena in the lateral jet/cross-flow interaction field are also measured using color high-speed camera. The growth of the interaction field is reconstructed and visualized three dimensionally.
