Fetch Limited Drag Coefficients
Boundary-Layer Meteorology, 1997Measurements made at a tower located 2 km off the coast of Denmark inshallow water during the Riso Air Sea Experiment (RASEX) are analyzedto investigate the behaviour of the drag coefficient in the coastal zone.For a given wind speed, the drag coefficient is larger during conditions ofshort fetch (2-5 km) off-shore flow with younger growing waves than ...

Drag coefficient in urban trees
Trees, 2020The drag force is frequently responsible for tree fall; however, its calculation depends on a rarely known parameter, namely, the drag coefficient. This paper reviews this topic. The pressure exerted by the wind on trees can generate large drag forces, which have been considered the most frequent causes for mechanical failure in trees.

Drag coefficient for amphibious house
Urban Water Journal, 2017AbstractRecently, flooding has become a serious issue and disaster in Malaysia. Therefore, it is crucial to search for a more effective flood mitigation approach in Malaysia. Amphibious house system is a new sustainable and flexible flood mitigation measure within a floating urbanization environment. Amphibious house has been designed based on buoyancy

BRIDGE PIERS—DRAG FORCE COEFFICIENTS
ISH Journal of Hydraulic Engineering, 2004ABSTRACT The rational approach for estimating afflux at bridge constrictions requires the knowledge of drag coefficient. This paper presents experimental investigations on the variation of drag coefficient with Reynolds number for piers with semicircular nose and tail and lens-shaped nose and tail considering the effects of flow contraction and length ...

Boundary-Layer Meteorology, 1973
Data on the relationship of the surface wind to the geostrophic wind at Porton Down, Salisbury Plain, are presented for various stability conditions and analysed in the light of the Rossbynumber similarity theory. For near-neutral conditions, the geostrophic drag coefficients for geostrophic wind speeds 5 to 15 m s-1 are close to those found by other ...

Planetary and Space Science, 1965
Abstract The drag of artificial earth satellites is reconsidered in the light of recent studies of gas-surface interactions and atmospheric composition. Between heights of 140 and 400 km at times of low solar activity, or heights of 140 and 600 km at times of high solar activity, the drag coefficient is almost independent of height, and at present ...

Computation of conductor drag coefficients
Journal of Wind Engineering and Industrial Aerodynamics, 1993Abstract Conductor drag coefficients are computed using large eddy simulation. A hybrid procedure in which the finite difference method is used to integrate the momentum equation and the finite element method to integrate the pressure equation is utilized in a nonorthogonal grid system.

Drag coefficients for tumbling satellites.
Journal of Spacecraft and Rockets, 1967Figure 3 shows how typical PLOT results are presented. For illustrative purposes, ROD is plotted as a function of normal countdown time, which is extended by the programmed hold. Gain in PLOT is plotted as a function of programmed hold-time; the gain is referenced to RCD for the normal countdown.
