碩士 === 國立臺灣大學 === 應用力學研究所 === 93 === The experiment is " droplet impact on liquid". that can product sound. so We have three part to do. First ; We use different droplet size and hight. that can impact on liquid and produce eight situation sound pressure. Second; We fix droplet diameter and variation high. That can compare sound pressure interrelated. Third; We use different droplet diameter and high that impact on liquid and to observe different phenomenon we get great conclusion. First; If we fix impact high. And to increase droplet diameter that can reduce sound frequency. Second; If we fix droplet diameter And to increase impact high that increase sound frequency. Third; We use different droplet diameter and impact high. We have a new find; The regular entrainment was occured.that is in droplet diameter from 5.7mm to 7.5mm and impact velocity 1.5m/s.The other one; We find, The droplet diameter is 10mm and the impact velocity is 1.4m/s then we can get large bubbles
