Visualization of a confined accelerated bubble
High-speed photography was used to study the collapse of a confined two-dimensional, air cavity in water, subjected to a propagating pressure disturbance. The 5–6 mm diameter cavity was confined in a rectangular duct. A sustained pressure disturbance was created by an accelerating piston in contact with the water 240 mm away from the bubble. The pressure increased from 0.1 MPa to about 0.12 MPa...
متن کاملInertially confined plasma in an imploding bubble
Models of spherical supersonic bubble implosion in cavitating liquids predict that it could generate temperatures and densities sufficient to drive thermonuclear fusion1,2. Convincing evidence for fusion is yet to be shown, but the transient conditions generated by acoustic cavitation are certainly extreme3–5. There is, however, a remarkable lack of observable data on the conditions created dur...
متن کاملAtomic Motions in Confined Polymer Films
FIGURE 2. The normalized elastic intensities in the HFBS detector at Q = 0.36 Å-1. The decrease in intensity at high temperatures reflects the presence of atomic motion in the thin polymer films. M properties at surfaces and interfaces often deviate from their bulk values. An example is viscoelastic properties that are important in many applications such as chemically amplified photoresists, lu...
متن کاملUltra-Fine Bubble Distributions in a Plant Factory Observed by Transmission Electron Microscope with a Freeze-Fracture Replica Technique
Water containing ultra-fine bubbles (UFB) may promote plant growth. But, as UFBs are too small to distinguish from other impurities in a nutrient solution, it is not known if UFBs survive transport from the water source to the rhizosphere. Here we use the freeze-fracture replica method and a transmission electron microscope (TEM) to observe UFBs in the nutrient solutions used in a crop-growing ...
متن کاملNumerical Simulation of Bubble Motions in a Gate Slot
Lagrangian-Eulerian numerical scheme for the investigation of bubble motion in turbulent flow is developed. The flow is analyzed in the Eulerian reference frame while the bubble motion is simulated in the Lagrangian one. Finite volume scheme is used, and SIMPLEC algorithm is utilized for the pressure and velocity linkage. The Reynolds stresses are modeled by the RSTM model of Launder. Upwind sc...
