Using the surface panel method to predict the steady performance of ducted propellers
surface panel method ducted propeller velocity potential iteration steady hydrodynamic performance
2011/9/13
A new numerical method was developed for predicting the steady hydrodynamic performance of ducted propellers. A potential based surface panel method was applied both to the duct and the propeller, and...
Interactions between Steady Won-Uniform Currents and Gravity Waves with Applications for Current Measurements
Interactions Gravity Waves Steady Won-Uniform Currents Current Measurements
2009/4/3
Interactions between steady non-uniform currents and gravity waves are generalized to include the case of a random gravity wave field. The Kitaigorodskii-Pierson-Moskowitz frequency spectrum is used a...
The steady-state circulation in a rectangular bay is studied numerically in a model of homogeneous water and vertical coasts. The competing influences of the surface winds and longshore currants flowi...
Upwelling Layers in a Steady, Wind-Driven Stratified Ocean
Upwelling Layers Wind-Driven Stratified Ocean
2009/4/2
A theoretical study is made of a region of steady upwelling adjacent to the eastern boundary of a stratified ocean. A multi-layered structure is required to satisfy all the boundary conditions. The ve...
The Influence of Longitudinal Variations in Wind Stress Curl on the Steady Ocean Circulation
Longitudinal Variations Steady Ocean Circulation Wind Stress Curl
2009/3/24
The influence of longitudinal variations in wind stress curt on the steady circulation in a rectangular ocean basin is investigated analytically in a linear barotropic model. It is shown that longitud...

Steady Wind-Driven Currents Shallow Water Variable Eddy Viscosity
2009/3/24
A theory is given for steady wind-driven currents in shallow water (friction depth comparable to total depth) in which the vertical eddy viscosity varies linearly with depth, from zero at the bottom t...

2009/3/9
Studies of frictionally induced motions of continental shell water near a large-scale ocean current reveal the possibility of strong coastal upwelling whenever the straight coast lies to the left of t...
Steady Wind-Driven Currents in a Large Lake with Depth-Dependent Eddy Viscosity
Wind-Driven Currents Large Lake Depth-Dependent Eddy Viscosity
2009/3/7
The theory of steady wind-driven currents in shallow water is extended to the case of a spatially variable eddy viscosity of the form ν=ν0eaz, where ν0 and a are constants and z is the vertical coordi...
A nonlinear inertial model of a steady-state coastal upwelling circulation is presented. The model describes a longshore equatorward current and countercurrent structure which is independent of any pa...
