【摘要】 在超音速流动中,进行了侧向喷流干扰特性的实验研究,研究了喷流压力、攻角、迎风侧及背风侧喷流对侧向喷流干扰特性的影响.结果表明,随喷流压力增大,喷流前的高压区向前扩展,喷流的包裹作用加强.有攻角时,背风侧喷流前的高压区更大,喷流包裹作用的影响区域前移,喷流的控制效果更好,这一趋势随攻角的增大更加明显.更多还原

【Abstract】 Experimental investigation of the lateral jet interaction have been performed in supersonic flows to study the effects of jet pressures, angle of attacks, leeward side jet or windward side jet on the jet interaction characteristics. The results indicated that with increasing of jet pressures, the high pressure region before lateral jet extended forward, and the wraparound effect strengthened. In the case of angle of attacks, the high pressure region before the leeward side jet enlarged, the region of jet wraparound effect moving forward, and the jet interaction control was more effective.更多还原
