摘要
利用定容弹及高速摄影,采用阴影法拍摄了喷雾图像,研究了喷射压力、环境气体密度对喷雾贯穿距及雾化锥角的影响。试验结果表明:随着喷射压力增大,喷雾贯穿距增大,雾化锥角变化不明显;随着环境气体密度的增大,喷雾贯穿距减小,雾化锥角增大。
Images of spray were taken by method of shadowgraph using optical constant volume chamber and high-speed camera, and the influence of injection pressure, ambient gas density on spray penetration and spray cone angle were studied. Results show that, with the increase of injection pressure, spray pen- etration increases while spray cone angle changes slightly; when chamber gas density increases, spray penetration decreases while spray cone angle increases.
