Abstract In bubble-assisted Liquid Hole Multipliers (LHM), developed for noble-liquid radiation detectors, the stability of bubble and electro-mechanical properties liquid-to-gas interface play a dominant role in detector performance. A model is proposed to evaluate static equilibrium configurations sustained underneath perforated electrode immersed liquid. For first time bubbles were optically...

Turbulence in the surfzone mixes momentum vertically, transmits stress to the sea bed, influences the structure of the crossand alongshore currents, and controls the suspension of sediment from the sea bed. In many coastal and shelf environments, the sea-bed is the primary source of tur­ bulence due to bottom induced shear. In the surfzone, the breaking-wave generated turbulence dominates over ...

Bubble cloud collapse is one of the most destructive forms of cavitation. However, numerical modeling of this phenomenon is challenging and involves strong bubble dynamics, bubble-bubble, and bubble-wall interactions. Here we consider an initially spherical cloud near a rigid wall and treat the cloud bubbly mixture as a continuum and the bubbles in the cloud as discrete singularities. These two...

A new Boundary Element Method software for simulating bubble dynamics is presented. This tool allows us to simulate a wide variety of scenarios, including external acoustic fields and multiple bubble interaction. We present results on the interaction between two oscillating bubbles in various configurations. Different sized bubbles under the effects of acoustic fields at different frequencies h...
