声场中气泡运动的混沌特性
Chaotic characteristics of gas bubble motion in acoustic field
摘要
Abstract
Considering liquid compressibility,the dynamical behaviors of gas bubble in acoustic field are investigated by regarding water as a work medium.The effects of acoustic frequency,acoustic pressure,initial radius of gas bubble,liquid surface tension,and viscosity coefficient on bubble motion state are numerically simulated.The relationship between cavitation treatment effect and gas bubble motion state is analysed.The results show that when the gas bubble motion is in a chaotic state,it is the most important factor for enhancing acoustic cavitation degradation of organic pollutants ability.关键词
