Bubbly shock propagation as a mechanism of shedding in separated cavitating flows [PDF]

, 2017
Stable attached partial cavitation in separated flows can transition to cloud shedding, and the mechanism of transition has been attributed to the presence of a re-entrant liquid jet.

Dynamics of jets produced by bursting bubbles

Physical Review Fluids, 2018
Sea spray is the main source of aerosols above the ocean. One of the pathways for sea spray production is through bubble bursting which ejects myriads of droplets. We present a detailed description of the velocity of jets formed by bubble bursting, obtained through extensive comparison between experimental results and numerical simulations for a wide ...

Numerical and experimental investigation of a confined plunging liquid jet system [PDF]

, 2012
In a confined plunging liquid jet (CPLJ) system, a liquid jet is allowed to fall in a partially submerged narrow downcomer tube. Liquid jet impingement at gas-liquid interface leads to entrainment of gas, which is dispersed down the downcomer tube in to ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Bubbly Jetの基礎的な性質 [PDF]

, 2017
Bubbly jet calculations are reported for the transition from jet to bubble plume. Bubbly jets are generated by releasing air bubbles and water from line source placed at the bottom. In the vicinity of line source, the velocity at the center of bubbly jet

Bubble measurements in a gas-liquid jet [PDF]

, 1996
Measurements have been carried out in the developing and fully developed regions of a free, axisymmetric, isothermal, air-water, bubbly jet. Three experiments have been conducted at a fixed jet-exit Reynolds number and gas superficial velocity using ...

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Bubble Bursting: Universal Cavity and Jet Profiles

Physical Review Letters, 2018
After a bubble bursts at a liquid surface, the collapse of the cavity generates capillary waves, which focus on the axis of symmetry to produce a jet. The cavity and jet dynamics are primarily controlled by a nondimensional number that compares capillary inertia and viscous forces, i.e., the Laplace number La=ργR_{0}/μ^{2}, where ρ, μ, γ, and R_{0} are

Non-intrusive measurements in a dispersed, bubbly, axisymmetric jet [PDF]

, 1997
Measurements have been carried out in the developing region of a free, axisymmetric, isothermal, air-water, bubbly jet. Two experiments have been conducted at a fixed jet-exit Reynolds number and gas superficial velocity with two distinctive average ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...
