摘　　要：通过Noble-Abel-Stiffend-Gas状态方程与修正的Keller-Miksis方程相结合,建立了研究具有传质传热和扩散效应的空化气泡动力学特性的一种新模型,即KM-NASG模型。对用新模型得到的结果与KMVdW模型给出的结果进行了比较。结果表明,由于2种模型所采用的状态方程不同,导致新模型给出的气泡崩溃深度略浅,内能、温度、压力的峰值变大,马赫数比KM-VdW模型的马赫数小。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.
