Abstract This paper investigates the growth dynamics of a vapor-gas bubble pressed against heating plate by buoyancy force. The shadow method was used to capture images, which were then automatically processed calculate size bubble. As expected, significantly depends on power. It found that ratio diameter height increases as it grows.

Simulating and predicting multiscale problems that couple multiple physics dynamics across many orders of spatiotemporal scales is a great challenge has not been investigated systematically by deep neural networks (DNNs). Herein, we develop framework based on operator regression, the so-called network (DeepONet), with long-term objective to simplify modeling avoiding fragile time-consuming “han...

A passive cavitation detector (PCD) identifies cavitation events by sensing acoustic emissions generated by the collapse of bubbles. In this work, a dual passive cavitation detector (dual PCD), consisting of a pair of orthogonal confocal receivers, is described for use in shock wave lithotripsy. Cavitation events are detected by both receivers and can be localized to within 5 mm by the nature o...

An Eulerian-Lagrangian approach is developed for the simulation of turbulent bubbly flows in complex systems. The liquid phase is treated as a continuum and the Navier-Stokes equations are solved in an unstructured grid, finite volume framework for turbulent flows. The dynamics of the disperse phase is modeled in a Lagrangian frame and includes models for motion of each individual bubble, bubbl...
