| 摘 要： | 研究了不同喷射位置、喷射马赫数和喷射角度的气体二次喷射混合流场的弓形激波形状。在二维矩形喷管内进行二次喷射试验，用纹影仪拍摄得到激波照片。将由照片换算得到了激波半径与用爆炸理论计算的结果相比较，证明爆炸波解在计算激波半径方面提供了与实验较符合的结果。

| Abstract: | Research for bow shock due to secondary gas injection was developed with different points of injection,Mach numbers and jet angles Experiments were carried out in two dimensional rectangular jet for photos taken with Schlieren apparatus The experimental data obtained from Schlieren photograph were compared with the results calculated from the blast wave theory It proved that the shock radium solutions from the blast wave agreement with the experiments |
