摘要 用高速摄影技术研究了高压气体膨胀驱动空气-水界面的瑞利-泰勒不稳定性,获得了空气-水界面的不稳定性清晰图像,得到气炮尖顶运动速度及湍流混合层高度增长速度与时间关系曲线。在横式激波管上用高速纹影诊断技术研究了激波作用空气-SF6界面的里克特迈耶-梅什科夫不稳定性,初步获得了实验图像,可清晰显示混合区变化过程。 High-speed photography is used to study the Rayleigh-Taylor instability of air-water interface driven by high-pressure exploding gas.Clear images illustrating the instability are obtained,along with the air bubble peak speed and turbulent mixing speed.The RM(Richtmyer-Meshkov) instability of air/SF6 interface driven by shock wave is also researched by using high-speed schlieren technique on the horizontal shock tube and primary experimental results are obtained,which show the change of the turbulent mixing region clearly.
