Lateral vibration of a water drop and its motion on a vibrating surface.
The resonant modes of sessile water drops on a hydrophobic substrate subjected to a small-amplitude lateral vibration are investigated using computational fluid dynamic (CFD) modeling. As the substrate is vibrated laterally, its momentum diffuses within the Stokes layer of the drop. Above the Stokes layer, the competition between the inertial and Laplace forces causes the formation of capillary...
متن کاملDrops bouncing on a vibrating bath
We present the results of a combined experimental and theoretical investigation of millimetric droplets bouncing on a vertically vibrating fluid bath. We first characterize the system experimentally, deducing the dependence of the droplet dynamics on the system parameters, specifically the drop size, driving acceleration and driving frequency. As the driving acceleration is increased, depending...
متن کاملVibrating Quantum Billiards on Riemannian Manifolds
Quantum billiards provide an excellent forum for the analysis of quantum chaos. Toward this end, we consider quantum billiards with time-varying surfaces, which provide an important example of quantum chaos that does not require the semiclassical (~ −→ 0) or high quantum-number limits. We analyze vibrating quantum billiards using the framework of Riemannian geometry. First, we derive a theorem ...
متن کاملThe Severity of Impacts During Low-Speed Water Skier Falls
Background: Little kinematic or kinetic information is available to understand risks associated with water skier falls. The present study assessed accelerations during low-speed falls and then contrasted these data against information obtained from automotive crash tests to better delineate risk of injury. The goal was to establish baseline impact information for low-speed falls during water sk...
متن کاملThe water falls but the waterfall does not fall: New perspectives on objects, processes and events
We challenge the widespread presumption that matter and objects are ontologically prior to processes and events, and also the less widespread but increasingly popular view that processes and events are ontologically prior to matter and objects. Instead we advance a third view according to which each of these pairs of categories is ontologically dependent on the other. In particular, taking a cu...
