... treatment of tumors. This model uses a fixed grid, multi-domain, interface tracking, direct numerical simulation method that treats all interfaces and boundaries as sharp discontinuities for high accuracy. In the current work, we examined effects of initial bubble size on the flows and wall stresses...

... thickness agrees with previous theories for semi-infinite bubble propagation. As the plug length decreases below the channel width, the trailing film thickness decreases, and for finite Re there is significant interaction between the leading and trailing menisci and their local flow effects. A recirculation...

...S. Naire; O. E. Jensen We consider a simple physical model for the reopening of a collapsed lung airway involving the unsteady propagation of a long bubble of air, driven at a prescribed flow-rate, into a liquid-filled channel formed by two flexible membranes that are held under large longitudinal...

...J. Creech; V. Divino; W. Patterson; P. J. Zalesky; C. E. Brennen It is possible to inject highly supersaturated aqueous solutions of gas through a small capillary into an aqueous environment without the formation of significant gas bubbles. Such a technique has considerable potential therapeutic...

... of data shown in Fig. 3 ; the open symbols represent Case ( i ) experiments, and the closed symbols represent semi-infinite bubble experiments for comparison (previously published, see 19 ). The curve represents a theoretical prediction for flow of semi-infinite bubbles 11 . The experimental results...

... a subject of debate in the literature. To study the influence of cavitation and gas content on the formation and growth of stable gas bubbles, a mock circulatory loop, which employed a Medtronic-Hall pyrolytic carbon disk valve in the mitral position, was used. A high-speed video camera allowed observation...

...Sean D. Chambers; Robert H. Bartlett; Steven L. Ceccio The purpose of this study was to determine the hemolytic potentials of discrete bubble cavitation and attached cavitation. To generate controlled cavitation events, a venturi-geometry hydrodynamic device, called a Cavitation Susceptibility...
