Numerical Simulation of Dam Breaking Using Smoothed Particle Hydrodynamics and Viscosity Behavior
meshless method smoothed particle hydrodynamics (SPH) dam breaking free surface flow
2011/9/9
Smoothed particle hydrodynamics (SPH) is a Lagrangian meshless particle method. It is one of the best method for simulating violent free surface flows in fluids and solving large fluid deformations. D...
Barotropic Rossby Waves in a Zonal Current：Effects of Lateral Viscosity
Barotropic Rossby Waves Zonal Current Lateral Viscosity
2009/3/24
The behavior of a barotropic Rossby wave in a zonal current is studied theoretically using a beta-plane ocean of constant depth in which the current depends only on latitude. The wave may be reflected...

2008/12/23
A variational optimal control technique is used to assimilate both meteorological and oceanographic observations into an oceanic Ekman layer model. An identical twin experiment is discussed first in w...
Quasi-linear Eddy-Viscosity Model for the Flux of Energy and Momentum to Wind Waves Using Conservation-Law Equations in a Curvilinear Coordinate System
Curvilinear Coordinate System Quasi-linear Eddy-Viscosity Model
2008/12/22
The airflow above ocean waves is calculated using a quasi-linear model—one in which the effect of the waves on the mean flow is taken into account. The model uses curvilinear coordinates, in which one...
