Drag Coefficients of Viscous Drops

Fluids Engineering, 2000
Abstract We have used a finite-difference scheme to solve the Navier-Stokes equations for the steady flow inside and outside viscous spheres in a fluid of different properties. Hence, we obtained the hydrodynamic forces and the steady-state drag coefficient of the spheres. The computational technique we have used enables us to extend the

Fetch Limited Drag Coefficients

Boundary-Layer Meteorology, 1997
Measurements 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 ...

Geostrophic drag coefficients

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 ...

Swell and the drag coefficient

Ocean Dynamics, 2015
Simultaneous measurements of waves and turbulent fluxes were collected from a moored surface buoy in the Philippine Sea. Waves were partitioned into their wind sea and swell components, and the ratio of swell to wind sea energy was used to assign a swell index. The 10-m neutral drag coefficient was calculated using the eddy correlation method.

Drag coefficient in urban trees

Trees, 2020
The 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.

Computation of conductor drag coefficients

Journal of Wind Engineering and Industrial Aerodynamics, 1993
Abstract 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 coefficient for amphibious house

Urban Water Journal, 2017
AbstractRecently, 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

Drag coefficients for tumbling satellites.

Journal of Spacecraft and Rockets, 1967
Figure 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.

On the drag coefficient of triangular profiles

Meccanica, 1988
Results of a laboratory study on the determination of the drag coefficient of triangular profiles simulating a train of sedimentary dunes are here presented. The study is carried out in a low speed wind tunnel by performing a direct measurement of the total drag force acting on one of the profiles and then subtracting the skin shear force to obtain the
