Visualization and Analysis of Vortex-Turbine Intersections ...

Characterizing the interplay between the vortices and forces acting on a wind turbine's blades in a qualitative and quantitative way holds the potential for significantly improving large wind turbine design. This paper introduces an integrated pipeline for highly effective wind and force field analysis and visualization. We extract vortices induced by a turbine's rotation in a wind field, and ...

tornado - Tornado safety | Britannica

tornado - tornado - Tornado safety: Tornadoes produce extremely hazardous conditions. The main dangers are caused by extremely high winds and flying debris. Little can be done to prevent heavy damage to structures that are directly hit by a tornado, though good building practices (such as securely fastening the roof of the house to the walls and securing the walls to the foundation) can reduce ...

US4070131A - Tornado-type wind turbine - Google Patents

Atmospheric wind is admitted tangentially into a vertically extending structure and directed against the interior curved surface of the structure to produce vortex flow. The structure is open ended and spaced from ground or connected to a ram-air subterranean tunnel. The vortex flow and corresponding low pressure core draws ambient and/or ram air into the bottom of the structure to drive a ...

Can it be a tornado if there isn't a funnel? | Stormtrack

According to the Glossary of Meteorology (AMS 2000), a tornado is "a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud." Literally, in order for a vortex to be classified as a tornado, it must be in contact with the ground and the cloud base.

This study demonstrates the use of two types of pendulums on a vortex bladeless wind (VBW) turbine: arc-shaped and disc-shaped. Here, the kinetic energy of the wind as input to the VBW turbine gets converted into useful electrical energy for both types of pendulums. Permanent magnets are attached to the pendulums and act as a piston to the generator, while a coil is made as the stator with ...

INTRODUCTION. A significant F1 tornado, with wind speeds estimated at 100 to 110 mph, produced an estimated $526,000 in damage as it moved through the downtown area of Miami around 1800 UTC (2:00 P.M. EDT) on May 12, 1997. The tornado developed just southwest of the city and first touched down in the Silver Bluff Estates area at approximately ...

Vortex - Wikipedia

The core of a vortex in air is sometimes visible because water vapor condenses as the low pressure of the core causes adiabatic cooling; the funnel of a tornado is an example. When a vortex line ends at a boundary surface, the reduced pressure may also draw matter from that surface into the core.
