声空化气泡的KM-NASG动力学模型
KM-NASG Dynamic Model of Acoustic Cavitation Bubble
摘要
Abstract
By combining the Noble-Abel-Stiffend-Gas equation of state with the modified Keller-Miksis equa-tion,a new KM-NASG model is established to study the dynamic characteristics of cavitation bubbles with mass transfer,heat transfer and diffusion effects.The results obtained by the new model are compared with the results given by the KM-VdW model.The results show that due to the different state equations adopted by the two mod-els,the bubble collapse depth given by the new model is slightly shallow,the peak value of internal energy,tem-perature and pressure becomes larger,and the Mach number is smaller than that of the KM-VdW model.关键词
