Baroclinic Vortices over a Sloping Bottom
Nonlinear quasigeostrophic flows in two layers over a topographic slope are considered. Scaling the lower layer potential vorticity equation yields two parameters which indicate the degree of nonlinearity in the lower layer. The first, u' (the strength of the deep flow divided by the product of the effective bottom slope and the squared length scale), is related to the advection of relative vor...
متن کاملExperiments on the Run-up of Solitary Waves over Sloping Bottoms
The objective of this study was to investigate experimentally solitary waves run-up on sloping beaches. Conducted in the Super wave flume(5m×5.2m×300m) and the Large wave flume(2m×2m×200m)at Tainan Hydraulics Laboratory (THL), solitary waves were generated by moving the wave board forward in the manner of ramp-trajectory and solitary-wave-trajectory separately to simulate the various of wave he...
متن کاملNumerical Modeling and Experiments for Solitary Wave Shoaling and Breaking over a Sloping Beach
This research deals with the validation of fluid dynamic models, used for simulating shoaling and breaking solitary waves on slopes, based on experiments performed at the Ecole Supérieure d’Ingénieurs de Marseille’s (ESIM) laboratory. A separate paper, also presented at this conference, reports on experiments. In a first part of this work, a fully nonlinear potential flow model based on a Bound...
متن کاملThe Evolution of Density-Driven Circulation Over Sloping Bottom Topography
The short timescale temporal ev~lution of buoyancy-driven coastal flow over sloping bottom topography is examined using a two-dimensional, vertically averaged numerical model. Winter shelf circulation driven by a coastal "point source" buoyancy flux is modeled by initiating a coastal outflow with density anomaly t into well-mixed shelf water. The nonlinear interaction between the time-varying v...
متن کاملEfficient numerical method for linear stability analysis of solitary waves
a r t i c l e i n f o a b s t r a c t In this paper we use a numerical relaxation algorithm to improve and generalize the obtainment of the perturbation eigenstates of nonlinear systems. As a model problem we consider the linear stability analysis of the vortex eigenstates of the cubic–quintic nonlinear Schrödinger equation. It is shown by numerical calculations that the relaxation algorithm pe...
