Dynamics of a cavitation bubble between oblique plates

Hemant J. J. Sagar et al.

Summary: Experiments were conducted to study the collapsing behavior of a cavitating bubble formed between two symmetrically arranged oblique plates. By generating a cavitation bubble using a focused laser beam, it was observed that the initial position of the bubble greatly influenced its dynamics. The results of this study provide insights into the dynamics of bubbles generated between oblique plates, which can contribute to various applications such as microfluidic pumping techniques and biomedical devices.

Cavitation bubble dynamics and microjet atomization near tissue-mimicking materials

A. B. Sieber et al.

Summary: Considerable interest has been devoted to the interactions between cavitation bubbles and tissue-mimicking materials in recent years, as they have promising applications in medicine and biomedical sciences. The fluid-structure interaction between cavitation bubbles and elastic surfaces triggers unique collapse dynamics, including bubble splitting and microjetting phenomena that can cause damage. This study investigates the effect of boundary elasticity and bubble-surface distance on the dynamics of cavitation bubbles and the velocity of microjets. High-speed imaging techniques are used to track the bubble dynamics, with a focus on the formation and evolution of microjets. The study provides evidence of the atomization of liquid microjets within the bubble, followed by the establishment of fully liquid microjets. Supersonic velocities of up to 2000 m/s are achieved by the atomized portion of the microjet, while fully developed liquid microjets travel at averaged speeds of up to 1000 m/s. A numerical model based on the boundary integral method shows remarkable agreement with experimental observations.

The role of acoustofluidics and microbubble dynamics for therapeutic applications and drug delivery

S. I. Kaykanat et al.

Summary: Targeted drug delivery using nanoparticles as nanocarriers has been proposed to reduce the toxic effects of conventional therapeutic methods. However, biological barriers hinder effective drug delivery. To overcome these barriers, different targeting strategies and nanoparticle designs have been developed. Ultrasound, combined with microbubbles, is a new and safe method for drug targeting. Microbubbles oscillate under ultrasound, increasing endothelial permeability and enhancing drug uptake at the target site. This technique reduces drug dosage and minimizes side effects. This review provides an overview of biological barriers and targeting strategies, focusing on acoustically driven microbubbles for biomedical applications. The theoretical part covers the historical development of microbubble models under different conditions, and discusses the current state and future directions.

Three-dimensional bubble jetting inside a corner formed by rigid curved plates: Boundary integral analysis

Abdolrahman Dadvand et al.

Summary: The three-dimensional dynamics of a transient bubble inside a corner formed by two rigid curved parabolic plates is studied using the boundary integral method based on potential flow theory. The bubble's expansion and collapse phases, as well as the formation of a liquid jet towards the corner, are investigated for different corner angles and focal lengths of the parabolas. The position and symmetry of the bubble's oscillation and the shape and velocity of the ensuing liquid jet are found to be influenced by the corner angle and the closer wall.

A unified theory for bubble dynamics

A-Man Zhang et al.

Summary: In this study, we proposed a novel theory for the dynamics of oscillating bubbles. This theory takes into consideration various factors such as boundaries, bubble interaction, ambient flow field, gravity, bubble migration, fluid properties, and surface tension. We validated the theory with experimental data and compared it with classical theoretical models, demonstrating its advantages. Additionally, we applied the theory to model complex multi-cycle bubble interaction and gained new insights into inter-bubble energy transfer and pressure wave coupling.

Numerical investigation of the cavitation bubble near the solid wall with a gas-entrapping hole based on a fully compressible three-phase model

Jianyong Yin et al.

Summary: The influence of a solid surface with gas-containing cavities on the dynamical behaviors of bubbles was studied. The predicted bubble shape was validated with experimental photos, and good agreement was achieved. It was found that the gas-entrapping hole on the solid wall affects the morphology of both the bubble and liquid jet and shortens the bubble's first oscillation period.

Ring Vortex Dynamics Following Jet Formation of a Bubble Expanding and Collapsing Close to a Flat Solid Boundary Visualized via Dye Advection in the Framework of OpenFOAM

Max Koch et al.

Summary: A bubble expanding and collapsing near a solid boundary induces a liquid jet towards the boundary, leaving a torus bubble and persistent vortices in the liquid. The vortices, with different rotation directions and varying amplitude, are studied numerically and compared to experiments. The study reveals a transition interval where the dominating rotational direction of the fluid flow changes, which is accompanied by increased erosion of the solid surface.

Summary: The dynamics of a gas bubble close to intact and perforated concave rigid plates in an unlimited liquid domain were investigated using the boundary element method combined with the finite difference method. The results showed that the behavior of the bubble varied depending on the bubble-plate distance, hole size, and bubble-hole distance. Different scenarios of bubble oscillation were observed, including the presence of liquid jets pointing towards and away from the plate.

Dynamics of a Laser-Induced Bubble above the Flat Top of a Solid Cylinder-Mushroom-Shaped Bubbles and the Fast Jet

Max Koch et al.

Summary: This study investigates the dynamics of a laser-induced bubble on top of a solid cylinder through experimental and numerical methods. The research findings show that when the bubble is generated near the flat top of the cylinder and its maximum radius exceeds that of the flat top surface, it collapses into a mushroom shape with a footing on the cylinder, a long stem, and a hat-like cap. Depending on the size and distance of the bubble to the top of the cylinder, the cap may collapse, resulting in a thin, fast liquid jet into the stem.

The application of flow to an ultrasonic horn system: Phenol degradation and sonoluminescence

Richard James Wood et al.

Summary: The study found that the degradation of phenol in an ultrasonic horn system can be enhanced with the application of fluid flow, leading to an increase in degradation as the flow rate increases. There is a strong correlation between phenol degradation and sonochemical processes, indicating that degradation occurs through an oxidative process. The intensity of sonoluminescence can be increased with flow, suggesting that flow changes the properties of bubbles to cause active bubbles to collapse with greater intensity.

Summary: The study systematically examines the cavitation-induced wall shear stress on rigid boundaries as a function of liquid viscosity and stand-off distance using axisymmetric VoF simulations. The simulations accurately predict the dynamics of bubbles and the liquid film thickness before collapse. The spatial and temporal wall shear stress is analyzed in detail, showing inward stress from shrinking bubbles and outward stress from expanding bubbles and jet spreading.

Summary: Understanding the acoustic oscillation of microbubbles near boundaries is crucial for designing ultrasonic biomedical devices and surface cleaning technologies effectively. This study investigated microbubble oscillation between two curved rigid plates in a planar acoustic field using the boundary integral method, and evaluated the effects of wave direction and horizontal standoff distance on bubble dynamics. It was discovered that the jet velocity and high-pressure region in acoustic bubbles are significantly larger than those in gas bubbles.
