Dynamics and measurement of cavitation bubble

Science China(Physics,Mechanics & Astronomy) 2006年第4期49卷 385-395页

作者： CHEN Weizhong LIU ya'nan HUANG Wei gao Xianxian Key Laboratory of Modern Acoustics and Institute of Acoustics Nanjing University Nanjing 210093 China Key Laboratory of Modern Acoustics and Institute of Acoustics Nanjing University Nanjing 210093 China Key Laboratory of Modern Acoustics and Institute of Acoustics Nanjing University Nanjing 210093 China Key Laboratory of Modern Acoustics and Institute of Acoustics Nanjing University Nanjing 210093 China

Based on the introduction of international progress, our investigations on acoustic cavitation have been reported. Firstly we considered the cavity's dynamics under the drive of the asymmetrical acoustic pressure. An aspheric dynamical model was proposed and a new stable and aspheric solution was found in numerical simulation of the theoretical framework of the aspheric model. Then, a dual Mie-scattering technique was developed to measure the cavity's aspheric pulsation. A significant asynchronous pulsation signal between two Mie-scattering channels was caught in the case of large cavity driven by low acoustic pressure. As a direct deduction, we observed an evidence of cavity's aspheric pulsation. Furthermore, we studied the dependency of the asynchronous pulsation signal on the various parameters, such as the amplitude and frequency of the driving acoustic pressure, and the surface tension, viscosity and gas concentration of the liquid. Finally, we introduced a new numeric imaging technique to measure the shapes of the periodic pulsation cavities. The time-resolution was in the order of 20 ns, one order of magnitude lower than that in the previous work, say, 200 ns.

作者： ya-nan gao Ziyao ZHANG Faculty of International Language Education Hebei Foreign Studies University College of Mathematics and Computer Science Hanjiang Normal University

In this paper, a new type of entropy, directional preimage entropy including topological and measure theoretic versions for ■-actions, is introduced. Some of their properties including relationships and the invariance are obtained. Moreover, several systems including ■-actions generated by the expanding maps, ■-actions defined on finite graphs and some infinite graphs with zero directional preimage branch entropy are studied.
