Drag coefficient reduction at very high wind speeds

[1] The correct representation of the 10-m drag coefficient for momentum (K10) at extreme wind speeds is very important for modeling the development of tropical depressions and may also be relevant to the understanding of other intense marine meteorological phenomena. We present a unified boundary layer model for (K10), which takes account of both the wave field and spray production, and asympt...

Consider a non-spherical elephant: computational fluid dynamics simulations of heat transfer coefficients and drag verified using wind tunnel experiments.

Animal momentum and heat transfer analysis has historically used direct animal measurements or approximations to calculate drag and heat transfer coefficients. Research can now use modern 3D rendering and computational fluid dynamics software to simulate animal-fluid interactions. Key questions are the level of agreement between simulations and experiments and how superior they are to classical...

Sphere Drag and Heat Transfer

Modelling fluid flows past a body is a general problem in science and engineering. Historical sphere drag and heat transfer data are critically examined. The appropriate drag coefficient is proposed to replace the inertia type definition proposed by Newton. It is found that the appropriate drag coefficient is a desirable dimensionless parameter to describe fluid flow physical behavior so that f...

An Estimate of the Geosat Altimeter Wind Speed Algorithm at High Wind Speeds

Existing wind speed algorithms for satellite altimeters have been developed from data in the range 0 to 20 m/s. At higher wind speeds the available algorithms diverge alarmingly. By comparing Geosat altimeter values of the radar cross section with model predictions of the surface winds during satellite overpasses of tropical cyclones, a wind speed algorithm valid for wind speeds between 20 and ...

Lift and drag in intruders moving through hydrostatic granular media at high speeds.

Recently, experiments showed that forces on intruders dragged horizontally through dense, hydrostatic granular packings mainly depend on the local surface orientation and can be seen as the sum of the forces exerted on small surface elements. In order to understand such forces more deeply, we perform a two-dimensional soft-sphere molecular dynamics simulation, on a similar setup, of an intruder...
