Low-Temperature Hydrothermal Plumes in the Near-Bottom Boundary Layer at Endeavour Segment,Juan de Fuca Ridge
Low-Temperature Hydrothermal Plumes Near-Bottom Boundary Layer Endeavour Segment,Juan Fuca Ridge
2015/7/14
Low-temperature (typically 5–75°C) fluid, commonly referred to as "diffuse" hydrothermal flow, emanates from fractures over a significant portion of the Juan de Fuca Ridge seafloor in the Northeast Pa...
Unstructured Grid Immersed Boundary Method for Numerical Simulation of Fluid Structure Interaction
fluid structure interaction immersed boundary method VOS unstructured grids finite volume method
2011/9/9
This paper presents an improved unstructured grid immersed boundary method. The advantages of both immersed boundary method and body fitted grids which are generated by unstructured grid technology ar...
Using a Time-domain Higher-order Boundary Element Method to Simulate Wave and Current Diffraction from a 3-D Body
wave-current diffraction time-domain simulation drift force higher-order boundary element method
2011/9/9
To study wave-current actions on 3-D bodies a time-domain numerical model was established using a higher-order boundary element method (HOBEM). By assuming small flow velocities, the velocity potentia...
Intensity of convective motions in marine atmospheric boundary layer retrieved from ocean surface radar imagery
Intensity of convective motions marine atmospheric boundary layer ocean surface radar imagery
2009/11/9
The paper focuses on the occurrence and development of coherent structures observed in the atmosphere above ocean under natural conditions. Microwave imaging radars are suggested as data take instrume...
Surface mixing and biological activity in the four Eastern Boundary Upwelling Systems
Surface mixing biological activity four Eastern Boundary Upwelling Systems
2009/10/30
Eastern Boundary Upwelling Systems (EBUS) are characterized by a high productivity of plankton associated with large commercial fisheries, thus playing key biological and socio-economical roles. Since...
The Coastal Boundary Layer in Lake Ontario：Part II. The Summer-Fall Regime
Coastal Boundary Layer Lake Ontario The Summer-Fall Regime
2009/4/3
Field observations on coastal currents near Oshawa on the north shore of Lake Ontario during summer and fall are described. The technique of observations (flag-station chain) has been given in Part I,...
The Coastal Boundary Layer in Lake Ontario. Part I: The Spring Regime
Lake Ontario Coastal Boundary Layer Spring Regime
2009/4/3
Originally prompted by a desire to search for theoretically predicted “coastal jets,” an extensive series of observations on currents in the coastal zone near Oshawa, in Lake Ontario, were carried out...
Some simple momentum advection effects are considered in a current aligned with the y axis on which there is superimposed a "cross" flow in the x-z plane. The cross flow coupled with horizontal shear ...
A Possible Mechanism for Boundary Layer Mixing and Layer Formation in a Stratified Fluid
Possible Mechanism Layer Formation Boundary Layer Mixing Stratified Fluid
2009/3/9
A plate tilted at 42° from the horizontal is oscillated along its length with frequency ω and amplitude a in a linearly stratified fluid (salt water) of kinematic viscosity ν. If the Reynolds number R...
Surface Thermal Boundary Condition for Ocean Circulation Models
Surface Thermal Boundary Condition Ocean Circulation Models
2009/3/9
By employing a heat budget analysis appropriate to zonally and time averaged conditions within the atmosphere, it is shown that the net downward heat flux Q at the ocean's surface can be expressed as ...
Baroclinic Boundary Currents and Long Edge-Waves in Basins with Sloping Shores
Baroclinic Boundary Currents Sloping Shores Long Edge-Waves
2009/3/9
Earlier work on baroclinic “coastal jets” and Kelvin waves in constant-depth basins is extended to basins with sloping shores. Baroclinic coastal jets are again found to be set up by an inflow or outf...
Measurements of the Turbulent Boundary Layer under Pack Ice
Turbulent Boundary Layer Pack Ice
2009/3/7
The mean and turbulent flow structure under pack ice was measured during the 1972 AIDJEK pilot study with small mechanical current meter triplets at eight levels in the planetary boundary layer. CTD p...
Application of a “Radiation-Type” Boundary Condition to the Wave, Porous Bed Problem
Radiation-Type Porous Bed Problem Boundary Condition
2009/3/7
The problem of a small-amplitude wave propagating over a flat porous bed is reanalyzed subject to the bottom boundary condition where u represents the horizontal velocity in the fluid,s represents the...

Residual Flow Turbulent Bottom Layer Beneath Waves
2009/3/7
A model is considered of the turbulent bottom boundary layer beneath waves. Closure is effected at the level of the turbulent energy equation and numerical solutions are obtained by a combination of f...
