Recoil Cavity Formation and Collapse for Drop Impact on Sieves [PDF]
Small ScienceThe principle underpinning most printing technologies rely on is the formation and subsequent collapse of cavities to generate high‐speed jets or droplets.

Study on Ground Collapse of Covered Karst Soil Caves by Sudden Drop of Groundwater [PDF]
Advances in Civil Engineering, 2021 In this study, the ellipsoidal soil cave with vertical collapses in the covering karst area is studied. Based on certain assumptions, the mechanical model of karst collapse caused by groundwater drop was established.

Evaluation of Biosurfactant Property within Plant Probiotic Species
Journal of Pure and Applied Microbiology, 2023 The present study focusses on proving the biosurfactant activity of the 7 isolated bacterial strains. Plants could not absorb enough nutrients as a result of contamination in the soil. This contaminants can be chemical pollutants or oil spillage.

CC(T) Specimen Load-Bearing Capacity Related to Yield Strength and Upper-Shelf Charpy-V Energy
Applied Mechanics, 2021 The load-bearing capacity of a CC(T) specimen (Center-Cracked Tension) in the ductile fracture regime is usually controlled by plastic collapse. If the material’s tearing resistance is sufficiently low, the load-bearing capacity can drop below the ...

Drops: The collapse of capillary jets [PDF]
Proceedings of the National Academy of Sciences, 2002 The appearance of fluid filaments during the evolution of a viscous fluid jet is a commonly observed phenomenon. It is shown here that the break-up of such a jet subject to capillary forces is impossible through the collapse of a uniform filament.

Dynamics of Collapse of Air Films in Drop Impact [PDF]
Physical Review Letters, 2012 Liquid drops hitting solid surfaces deform substantially under the influence of the ambient air that needs to be squeezed out before the liquid actually touches the solid. Nanometer- and microsecond-resolved dual wavelength interferometry reveals a complex evolution of the interface between the drop and the gas layer underneath. For intermediate impact

On the collapse pressure of armored bubbles and drops [PDF]
The European Physical Journal E, 2015 Drops and bubbles wrapped in dense monolayers of hydrophobic particles are known to sustain a significant decrease of their internal pressure. Through dedicated experiments we investigate the collapse behavior of such armored water drops as a function of the particle-to-drop size ratio in the range 0.02-0.2.

Conical focusing: mechanism for singular jetting from collapsing drop-impact craters
Journal of Fluid Mechanics, 2023 Fast microjets can emerge out of liquid pools from the rebounding of drop-impact craters, or when a bubble bursts at its surface. The fastest jets are the narrowest and are a source of aerosols both from the ocean and from a glass of champagne, of importance to climate and the olfactory senses. The most singular jets, which we observe experimentally at
