Control of Flow around an Oscillating Plate for Lift Enhancement by Plasma Actuators
Applied Sciences, 2019 During insect flight, a feathering motion of the wing’s controls vortex shedding for lift enhancement. In this study, in order to control the flow around a wing flapping with simplified sinusoidal motion, plasma actuators were introduced to ...

Acceleration of bouncing balls in external fields
, 1994 We introduce two models, the Fermi-Ulam model in an external field and a one dimensional system of bouncing balls in an external field above a periodically oscillating plate. For both models we investigate the possibility of unbounded motion.

THE SEPARATION OF FOOD MIXTURES WITH FINELY DIVIDED FRACTIONS
Современная наука и инновации, 2022 The proposed method of separation is as follows. First, there is a vibrational movement of the bulk mixture down between two vertically horizontally oscillating plates during interactions with each plate in each oscillation period to break the bonds ...

The effects of thermal radiation and viscous dissipation on MHD heat and mass diffusion flow past an oscillating vertical plate embedded in a porous medium with variable surface conditions [PDF]
Theoretical and Applied Mechanics, 2012 This investigation is undertaken to study the hydromagnetic flow of a viscous incompressible fluid past an oscillating vertical plate embedded in a porous medium with radiation, viscous dissipation and variable heat and mass diffusion.

Swimming of a Waving Plate [PDF]
, 1960 The purpose of this paper is to study the basic principle of fish propulsion. As a simplified model, the two-dimensional potential flow over a waving plate of finite chord is treated.

Loading of quartz oscillator plates
Journal of Research of the National Bureau of Standards, 1952 The effects of physically loading the surface of two types of piezoelectric quartz oscillator plates have been experimentally investigated. Various amounts of Wood's metal were applied to different parts of the crystal surfaces. Thickness-shear-mode plates were benefited only when the metal was applied on or near the active central area of the plate ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Natural convection flow near a vertical plate that applies a shear stress to a viscous fluid. [PDF]
PLoS ONE, 2013 The unsteady natural convection flow of an incompressible viscous fluid near a vertical plate that applies an arbitrary shear stress to the fluid is studied using the Laplace transform technique. The fluid flow is due to both the shear and the heating of
