Numerical Study of Cylinder Drag Coefficient Reduction Using Passive Flow Control [PDF]
In this study, the cylinder drag coefficient is reduced by using passive flow control. Installing a flat plate in two heights and different longitudinal distances in upstream flow increases the upstream flow momentum of the cylinder, leading to the ...

Influence of Porosity on Drag Coefficient of Perforated Road Signs
To ensure the structural stability of road signs against strong gusts of wind, perforated road signs with sign boards perforated at regular intervals have been adopted for use in urban road infrastructure. However, ASCE 7-22 standards do not consider the

Geostrophic drag coefficients over sea ice [PDF]
The geostrophic drag coefficient, Cg ≡ u*/G, and turning angle, α were measured October through November 1988 from a 120 km array of 6 drifting buoys and a drifting ship in the northern Barents Sea/Arctic Ocean during CEAREX; u* is the friction velocity, G is the geostrophic wind, and α is the angle between surface stress and equation image .

Turbulent drag on a low-frequency vibrating grid in superfluid He-4 at very low temperatures [PDF]
We present measurements of the dissipative turbulent drag on a vibrating grid in superfluid He-4 over a wide range of (low) frequencies. At high velocities, the dissipative drag is independent of frequency and is approximately the same as that measured ...
