【摘要】 对空泡在自由面或固壁面附近溃灭辐射噪声的规律进行了实验研究，不仅讨论了自由面及固壁面对辐射噪声的影响，还讨论了空泡中心距边界面的距离对辐射噪声的影响。其中空泡是应用调Q－YAG脉冲激光器产生，该方法在国内尚属首次，得到的实验结果与经典Vogel激光实验结果及作者的数值结果相吻合。更多还原

【Abstract】 The noise radiated by cavitation bubble collapsing near free surface or solid wall is studied experimentally.Cavitation bubble is generated using a Q-switched YAG impulse laser. The effects of the boundary properties and the distance between bubble and boundary, as well as the laser energy, on the acoustic radiation during cavitation bubble collapsing near free surface or solid wall are analyzed. The results are consistent with the classic experimental results of Vogel & Lauteborn and the author’s numerical results.更多还原
