Worthington jet physics. Feb 26, 2018 · Applied Physics Letters ( IF 3. Aug 29, 2022 · We characterize both peaks and elucidate how they relate to the different stages of the drop impact process. Feb 26, 2018 · The present study uses high-speed visualization of droplet impact on a superhydrophobic surface to understand jet initiation in terms of the collapse of an air cavity. There are two main components — the V-shaped tuck and the underwater motion. Here we present a novel phenomenon related to the impact of viscoelastic droplets on non-wettable substrates. The time at which the second peak appears coincides with the formation of a Worthington jet, emerging through flow focusing. This happens because when the sphere hits the water, it forces the liquid around it to move, generating energy that contributes to the formation of the jet. Jun 5, 2025 · In this video, researchers break down the physics of the move and how it creates an enormous splash. In fluid dynamics, drop impact occurs when a drop of liquid strikes a solid or liquid surface. 6 Submission Guide >) Pub Date: 2018-02-26 , DOI: 10. Sep 1, 2020 · In this paper, air cavity and Worthington jet formations due to the entrance of a hydrophilic steel sphere into three different target liquids are stu… Jul 16, 2022 · The retraction of an impacting droplet on a non-wetting substrate is often associated with the formation of a Worthington jet, which is fed by the retracting liquid. We reveal that the The typical diameter of the jet is tens or hundreds of micrometer and the jet velocity Ujet reaches close to or more than 10 folds of the impact velocity of the droplet. Feb 4, 2025 · Worthington jets occur when a solid sphere enters a body of water, creating a vertical column of liquid that can shoot high into the air. Although the growth of the jet as well as its tip velocity is predicted from similar cases to the droplet impact, the mechanism of the jet Jul 29, 2009 · Helped by the careful analysis of their experimental data, Worthington (1897) described roughly the mechanism underlying the formation of high-speed jets ejected after the impact of an axisymmetric solid on a liquid-air interface. Here, we investigate the Worthington jets generated during the water entry of solid spheres with no cavity formed experimentally and theoretically. The resulting outcome depends on the properties of the drop, the surface, and the surrounding fluid, which is most commonly a gas. 5020085 Ken Yamamoto, Masahiro Motosuke, Satoshi Ogata Deformation of liquid droplets by impingement induces Worthington jet in certain range of the impact velocity. 19,21–23 The generation and growth of the Worthington jet is modeled as a shrinking conical air cavity12,13,17,24: the cavity is axisymmetrically squeezed and collapsed. A non-Newtonian rheology of the liquid is known to affect the retraction of the impacting droplet. 1063/1. Heights of the continuous Worthington jet are recorded for each time step, and average maximum heights obtained are again compared to Froude and Weber numbers. There is no information about the reason behind the generation of the Worthington jet, it seems to me that there is something like a restoring force when the two cavities separate. In this work we combine detailed boundary-integral simulations with analytical modeling to describe the formation and break-up of such Worthington jets in two common Mar 16, 2022 · Worthington jet generated by a drop impacting onto an aqueous pool will make the secondary droplets and aerosols splash into the air, causing air poll… In the hydrophobic cases, the Worthington jet results from the collapse of the cavity formed below the free surface. . Dec 21, 2024 · Water entry problem has extensive applications in numerous areas of nature, industry, and science. eig7jse jcon mijt seamys 8bzpfos y2 or gewh 7rkdomwr pint
