The water wave generation by wave paddle and a freely falling rigid body are examined by using an Incompressible Smoothed Particle Hydrodynamics (ISPH). In the current ISPH method, the pressure was evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure Poisson equation contains both of divergence free velocit...

This paper describes the characteristics of small-amplitude waves generated by a sinusoidally oscillating, inclined paddle-type wavemaker operating in a constant-depth channel. Two-dimensional, linearized potential flow is assumed. A semi-analytical method, the boundary collocation method, is used to establish the relationship between wave amplitude and paddle stroke. The numerical results are ...

A vertically discretized multi-paddle wavemaker is proposed that generates various wave types without the depth-invariant flow condition limitation associated with conventional piston type wavemakers. first-order mathematical formulation for paddle stroke derived and used to selectively generate free surface waves similar either or flap wavemakers, depending on number of utilized paddles. The f...

The copper paddle-wheel is the building unit of many metal organic frameworks. Because of the ability of the copper cations to attract polar molecules, copper paddle-wheels are promising for carbon dioxide adsorption and separation. They have therefore been studied extensively, both experimentally and computationally. In this work we investigate the copper-CO2 interaction in HKUST-1 and in two ...

Abstract Laboratory measurements of the interaction between high‐frequency (HF) wind‐waves and low frequency (LF) paddle waves are presented. The were made in a wind‐wave flume with wind propagating same direction. primary objective is to examine physical mechanisms proposed explain suppression due presence swell (here waves). For this purpose, precise time scale temporal transition from wind‐o...

conclusions all paddle-boarding injuries were sustained by individuals who surf waves on a paddle-board, rather than paddle on calm water. despite concerns, paddle-board related injuries only accounted for 1% of 326 injuries suffered by surfers. we suggest equipment and practice modifications that may decrease the risk for injury and challenge the anecdotal theory that paddle-boarding injuries ...

BACKGROUND Stand-up paddle-boarding is an increasingly popular water sport; however no published data to our knowledge exists on the nature and type of injuries sustained in this sport. OBJECTIVES This study aims to describe the frequency, pattern, and mechanism of paddle-boarding injuries. MATERIALS AND METHODS Descriptive data of paddle-boarding injuries were collected using an interactiv...
