Worthington jet principle. There is a linear scaling regarding the axial velocity of the jet and the scaling coefficient increases with the Froude number. The vertical column of water that is produced is called a "Worthington jet. org/details/ Momentum balance dictates that there is a momentum jet opposite to this singular jet that can manifest as a sharp increase in normal force on the substrate. " It forms when the droplet is released from a sufficiently high position. 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. Sep 1, 2023 · The effect of gravity on the self-similarity of jet shape at late stage of Worthington jet development is investigated by experiment in the study. Jets refer to the ligament of fluid that extends normal to the water surface. This phenomenon cannot be simulated by the bell-shaped assumption. In the hydrophobic cases, the Worthington jet results from the collapse of the cavity formed below the free surface. 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. We explore three types of force reduction in this video: a sphere in a jet, a sphere following a smaller sphere, and a sphere impinging on a worthington jet. M. In this paper, we combine detailed boundary-integral simulations with analytical modelling to describe the formation of such Worthington jets after the impact of a circular disk on water. (Arthur Mason), 1852-1916: https://archive. Suggested Reading1) The splash of a drop by Worthington, A. Droplet impact on a pool of water. The splash of a drop. The jet is also called a Worthington jet. 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. As a result, while the theory gives a good description about the volume which reflects the total energy of the jet, it cannot catch the accumulation of fluid at the top of the jet, Sep 1, 2020 · When a solid object or a liquid droplet impacts the surface of a liquid pool, a jet or a column of fluid forms above the surface of the target liquid; this jet or column is called the “Worthington jet. . In addition, the particle image velocimetry (PIV) method is introduced to analyze the development of flow field. The purpose of our experiment was to observe the difference in the effect while varying the traveling object and the time lapse of each observation. The droplet creates a crater in the liquid surface and from the center of that crater protrudes a central jet and with enough energy the jet will pinch off and send more droplets upward (Inglis-Arkell 2015). . An interesting effect known as the Worthington Jet is observed when an object or material travels through the surface of a Newtonian fluid. ” A water droplet bounces off of the surface of a liquid pool and the impact generates a jet and radiating ripples. Sep 20, 2016 · A Worthington jet is formed when a droplet falls with enough velocity on a liquid surface (Inglis-Arkell 2015). 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.
