Effects of blade flexural rigidity on drag force and mass transfer rates in model blades
blade flexural rigidity model blades
2014/11/28
We created a model physical system to investigate the role of blade rigidity in setting forces and rates of mass
exchange for a blade exposed to unsteady flow in a vortex street. Using a combination ...
Drag coefficients for single coral colonies and related spherical objects
scleractinian corals drag force coral hydrodynamics
2014/4/1
Flows over and through coral canopies and isolated coral colonies are sometimes approximated using
arrays of spheres and cylinders, which may not adequately represent the effects of their complex geo...
A method for testing drag-reduction on riblet surfaces based on the Spalding formula
Spalding formula riblet surface drag-reduction testing
2011/9/13
This paper presents a method based on the Spalding formula for testing drag-reduction on riblet surfaces. Its advantage lies in that it is more convenient and yields more precise data compared with te...
Some Problems Associated with Wind Drag and Infrared Images of the Sea Surface
Wind Drag Sea Surface Infrared Images
2009/4/2
It is argued that there should be a close connection between fluctuations in infrared images of the sea and fluctuations in wind drag on the sea. The critical regions of wind speed, temperature, and s...
Mean Currents Driven by Topographic Drag over the Continental Shelf and Slope
Mean Currents Continental Shelf Topographic Drag
2009/1/13
A sequence of numerical simulations is described of wind-driven flow over irregular continental shelf topography. The model is barotropic, nonlinear, and forced by a periodic, spatially uniform alongs...
Topographic Drag Due to Barotropic Flow over the Continental Shelf and Slope
Topographic Drag Continental Shelf Barotropic Flow
2009/1/13
A barotropic model is formulated to investigate the topographic drag due to steady barotropic alongshore flow over the continental shelf and slope. The topography is extensive, irregular and of small ...
A Mechanism for the Increase of Wind Stress (Drag) Coefficient with Wind Speed over Water Surfaces：A Parametric Model
Wind Stress (Drag) Coefficient Wind Speed Water Surfaces Parametric Model
2009/1/10
A mechanism is proposed for a physical explanation of the increase in wind stress (drag) coefficient with wind speed over water surfaces. The formula explicitly incorporates the contribution of both w...
Kelvin Wave Propagation in a High Drag Coastal Environment
Kelvin Wave Propagation High Drag Coastal Environment
2009/1/6
Coastally trapped Kelvin waves in a model system of a flat half-planar ocean with a high-drag region of width L adjacent to the coast have properties that depend on L, and its drag, D0. For L less tha...
Depth Dependence of Bottom Stress and Quadratic Drag Coefficient for Barotropic Pressure-Driven Currents
Bottom Stress Barotropic Pressure-Driven Currents Quadratic Drag Coefficient
2009/1/6
A level 2½ turbulence closure model is used to investigate the dependence on water depth H of bottom stress τb and quadratic drag coefficient Cd for a steady barotropic pressure-driven current ...
Wave-Induced Stress and the Drag of c over Sea Waves
Wave-Induced Stress Drag Drag Sea Waves
2008/12/30
In this paper we are concerned with the effect of wind-generated, long gravity waves on the air flow. We study this example of resonant wave-mean flow interaction using the quasilinear theory of wind-...
Variational Estimation of the Wind Stress Drag Coefficient and the Oceanic Eddy Viscosity Profile
Variational Estimation Oceanic Eddy Viscosity Profile Wind Stress Drag Coefficient
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...
Laboratory Measurements of the Drag Force on a Family of Two-Dimensional Ice Keel Models in a Two-Layer Flow
Drag Force Two-Layer Flow Two-Dimensional Ice Keel Models
2008/12/12
A review of the upper structure of the Arctic Ocean and its overlying ice cover suggests that significant potential exists for the generation of internal wave fields by the deeper drafts of the pressu...
Observed Damping of Barotropic Seiches through Baroclinic Wave Drag in the Gullmar Fjord
Barotropic Seiches Baroclinic Wave Drag Gullmar Fjord
2008/11/18
Baroclinic wave drag, due to internal wave generation at steep topography, is shown to be a mechanism that effectively subdues barotropic seiches in fjords. A two-layer model for a fjord with a sill a...
Comments on “On the Obscurantist Physics of ‘Form Drag’ in Theorizing about the Circumpolar Current
Obscurantist Physics Circumpolar Current Form Drag
2008/10/27
In recent years the interest in the dynamical balance of the Antarctic Circumpolar Current (ACC) has seen a renaissance in oceanographic research. Various papers deal with the barotropic circulation i...
