Longshore current dislocation on barred beaches
[1] We present a numerical investigation of longshore currents driven by breaking waves on barred beaches. Alongshore inhomogeneity in the wave envelope or bathymetry leads to the generation of strong dipolar structures when the waves are breaking. The dynamics of these structures transfer momentum from the bar of the beach into the trough. This study is pursued using a new model that allows lo...
متن کاملEvolution Equations for Edge Waves and Shear Waves on Longshore Uniform Beaches
A general formalism for computing the nonlinear interactions between triads of coastally-trapped gravity and vorticity waves is developed. An analysis of the linearized problem reveals that gravity (or edge) waves and vorticity (or shear) waves exist as members of the same non-Sturm-Liouville eigenvalue problem, with unstable shear waves representing the complex eigenvalue portion of the result...
متن کاملReturn to Session SHEATH CIRCULATING CURRENT CALCULATIONS AND MEASUREMENTS OF UNDERGROUND POWER CABLES
In this paper, a calculation method of the sheath circulating current is introduced, taking the different grounding types, laying environment, structural parameters of cables into account. Due to the parameters in practice, the circulating currents in sheath are calculated and measured under the conditions of singlepoint grounding and both-end crossbonded grounding. The possible causes, which l...
متن کاملBoussinesq modeling of longshore currents
[1] A time domain Boussinesq model for nearshore hydrodynamics is improved to obtain the conservation of vertical vorticity correct to second order and extended for use on an open coast using longshore periodic boundary conditions. The model is utilized to simulate surface waves and longshore currents under laboratory and field conditions. Satisfactory agreement is found between numerical resul...
متن کاملToward uniform nanotubular compounds: synthetic approach and ab initio calculations.
We propose to synthesize a new class of single-walled nanotubular compounds (SWNCs) and investigate the interplay between their structural and electronic properties using ab initio density functional calculations. SWNCs are composed of cyclacenes of variable diameter interconnected by various linker compounds. Cyclacenes map directly onto and can be viewed as the shortest segments of (n,0) zigz...
