Drag Coefficient during Strong Typhoons [PDF]
Advances in Meteorology, 2013 Using data from wind towers during typhoons Hagupit and Nuri, drag coefficient was estimated. The relationship between drag coefficient and atmospheric stability was examined.

Numerical Study of Cylinder Drag Coefficient Reduction Using Passive Flow Control [PDF]
مهندسی مکانیک شریف, 2022 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
Applied Sciences, 2022 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]
Tellus A: Dynamic Meteorology and Oceanography, 1992 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 .

Atmosphere, 2021 The drag coefficient is essential for calculating the aerodynamic friction between air and sea. In this study, we regress a set of relationships between the drag coefficient and the wind speed for different wind ranges using an observational dataset that

Frontiers in Earth Science, 2022 Bottom drag coefficient is one of the key parameters in quantifying shelf hydrodynamics and sediment transport processes. It varies markedly due to dynamic forcing and bed type differences, so a set of empirical values have been used for beds of coarse ...

Buildings, 2023 This study aimed to estimate the drag and lift coefficients of the long-span bridge pylon using the finite volume method (FVM). The k-ω turbulence model was applied to analyze the behavior of wind flow around the pylon, yielding drag and lift coefficient

Surface Turbulence Reveals Riverbed Drag Coefficient [PDF]
Geophysical Research Letters, 2021 AbstractFlow in rivers and the coastal ocean is controlled by the frictional force exerted on the water by riverbed or seabed roughness. The frictional force is typically characterized by a drag coefficient Cd, which is estimated from bulk measurements and often assumed constant.
