Aerodynamic Behavior of Inclined Circular Cylinders-Cable Aerodynamics

open access: yesWind Engineers, JAWE, 1988
This study attempts to clarify of the mechanism of rain-wind induced vibration of the stay cables of a cable stayed bridge and to find an effective aerodynamic stabilization method. Through a series of wind tunnel tests the fundamental aerodynamic characteristics of a yawed and/or inclined circular Cylinder with and without rain were investigated.

The aerodynamics of sailing apparel

open access: yesProcedia Engineering, 2012
AbstractThe paper presents the effect of changes in sailing apparel on aerodynamic drag, starting from the assumption that drag reduction of sailing apparel will increase the speed of an Olympic class sailing boat (in this case the Laser, a single-handed Olympic dinghy), mainly on upwind courses. Due to the fact that literature on this specific subject

The Aerodynamics of Reacting Substances [PDF]

open access: yesProceedings of the National Academy of Sciences, 1939
Speaking broadly, the subject of aerodynamics is concerned not only with the forces exerted by a single fluid on solid bodies but also with the behavior of mixtures such as those which occur in the gasoline engine and in the atmosphere. In a complete study of the motion of a fluid attention must be paid to reactions between its constituents ...

On ionospheric aerodynamics [PDF]

open access: yesProgress in Aerospace Sciences, 1975
Abstract This paper presents theoretical methods to determine the gas dynamic and the electrostatic effects due to the interaction caused by a rapidly moving body in the ionosphere. The principles of the methods are derived from the kinetic theory of collision-free plasma. It is shown that the collective behavior of the collision-free plasma makes it
