Hydrodynamic Performance of Flapping-foil Propulsion in the Influence of Vortices
flapping-foil vortex numerical simulation hydrodynamic performance save energy
2011/9/9
Fish are able to make good use of vortices. In a complex flow field, many fish continue to maintain both efficient cruising and maneuverability. Traditional man-made propulsion systems perform poorly ...
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...
The Entrainment Influence on the Ocean Surface Layer in Tropical Latitudes
Entrainment Influence Tropical Latitudes Ocean Surface Layer
2009/3/9
A nonlinear, time-dependent, baroclinic model is developed for a zonally uniform, tropical, two-layer ocean on a north-south vertical section. The lower layer is infinitely deep, at rest, and at const...
The Influence of Wind on the Surface Layer of a Stratified Inlet：Part II. Analysis
Surface Layer Stratified Inlet Analysis
2009/3/7
Analysis of the wind and current data for Alberni Inlet demonstrates the strongly wind-dependent nature of the surface currents, especially at the diurnal frequency. In contrast, the response of the s...
The Influence of Wind on the Surface Layer of a Stratified Inlet：Part I. Observations
Surface Layer Stratified Inlet
2009/3/7
Observations are described in an experiment undertaken to determine the response of a stratified inlet to changing conditions of wind, tide and runoff. Time series of conductivity profiles taken in Al...
The Influence of the Directional Energy Distribution on the Nonlinear Dispersion Relation in a Random Gravity Wave Field
Directional Energy Distribution Nonlinear Dispersion Relation Random Gravity Wave Field
2009/3/7
The influence of the directional distribution of wave energy on the dispersion relation is calculated numerically using various directional wave spectrum models. The results indicate that the dispersi...
The Influence of Bottom Topography on Upwelling off Peru
Bottom Topography Upwelling off Peru
2009/2/18
The x-y-t, two-layer β-plane numerical model developed by Hurlburt (1974) is used to examine the upwelling system off Peru. The region off Peru from 14 to 15°30's is one of strong and persistent upwel...
Observed Surface Winds at Middleton Island, Gulf of Alaska and Their Influence on the Ocean Circulation
Observed Surface Winds Middleton Island Ocean Circulation
2009/2/16
Winds observed at an island in the Gulf of Alaska display a large annual signal with maximum easterlies in winter and weak easterlies in summer. For the northern Gulf of Alaska, the monthly mean Ekman...
Satellite Observations of the Influence of Bottom Topography on the Seaward Deflection of the Gulf Stream off Charleston, South Carolina
Bottom Topography Seaward Deflection Gulf Stream
2009/2/13
High-resolution thermal infrared data from the NOAA polar orbiting satellites are studied for the Gulf Stream between Florida and Cape Hatteras from the fall of 1974 to the spring of 1977. The sea sur...
