Bubble collapse and jet formation in corner geometries [PDF]
Physical Review Fluids, 2018 The collapse of a vapor bubble near a flat solid boundary results in the formation of a jet that is directed towards the boundary. In more complex geometries such as corners, predictions of the collapse cannot be made in a straightforward manner due to the loss of axial symmetry.

Jet mixing of water in crude oil pipelines [PDF]
, 1990 The jet mixing of water in crude oil pipelines by single nozzle and multi-nozzle mixers was studied by dividing the mixing domain into to three regions. the penetration. near field and farfield regions.

Mixing of a Cold Liquid Jet With a Boiling Liquid Stream [PDF]
, 1960 The turbulent mixing of a cold liquid jet with a stream of vapor bubbles and saturated liquid is analyzed for a single axial liquid jet. The cases where the issuing jet velocity is very much greater than and nearly equal to the free stream velocity are ...

Artificial Synaptic Device Based on Self‐Aligned c‐In2O3 TFTs With an Ultrathin MgO Interlayer
Advanced Materials Technologies, EarlyView.A coplanar synaptic thin‐film transistor based on crystalline In2O3 is demonstrated using a PECVD SiO2 gate insulator and an ultrathin MgO interlayer. The MgO interlayer suppresses excessive carrier density and may facilitate proton‐related interfacial polarization, resulting in stable counterclockwise hysteresis and synaptic behavior.

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Bubble tracking velocimetry for a steam jet
International Journal of Multiphase FlowThe time-averaged Effective Momentum Source (EMS) induced by steam injection into a subcooled water pool was measured in a Separate Effect Facility (SEF-POOL) under a wide range of injection conditions. Post-test simulations of large-scale pool experiments conducted in PANDA and PPOOLEX facilities indicate that diffusion of the momentum is another ...

Increasing gas-liquid contacting using a confined plunging liquid jet [PDF]
, 2003 The plunging liquid jet bubble column is an effective device for gas-liquid contacting. Small bubbles are formed in a high-shear region surrounding the plunging jet, leading to high interfacial area per unit volume of gas.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Effects of aspect ratio and gravity level on opposed bubbly jets [PDF]
, 2010 Numerical simulations of bubbly flows in an opposed-jet configuration have been carried out in a two-dimensional domain. The effects of aspect ratio and gravity level on the resulting flow have been considered.

Bubble Characteristics in the Buoyancy Region of a Vertical Bubbling Jet.
ISIJ International, 1992 The flow field in a vertical bubbling jet in a cylindrical vessel with bottom blowing can be divided into four regions. They are named the momentum, transition, buoyancy and surface regions in order of increasing distance from the nozzle exit. In a previous paper, bubble behavior characterized by gas holdup, bubble frequency, bubble rising velocity and
