wind pressure [′win ‚presh·ər] (mechanics) The total force exerted upon a structure by wind. Also known as velocity pressure. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. ...
The wind speed profile tends to a lower speed as it moves closer to the ground level. This is designated as wind shear. It is found that wind velocity increases with height above the ground according to formula [4] [2–8]. The rate of change strongly depends upon the roughness of the...
(pressure/transonic velocity) environment so as to obtain a colorful oil flow experiment image with high quality; and the colorful oil flow experiment image is used for analyzing airflow state of the model surface so as to realize high speed wind tunnel multi-color oil flow experiment and ...
The wind was directed towards the shore, and we estimated the wind drift velocity to be 3% of the wind speed, which was about 12 cm/s. When summing the wind drift and the mean current of 17 cm/s measured in the upper layer at a depth of 1 m, one comes to the value of the ...
(1980)revised the procedure of theGLFmethod to calculate the along-wind response of structures by modifying the Monte Carlo algorithm that was used to generate the fluctuating response.Solari (1993b,1993b) developed a procedure to treat the peakwind velocityand pressure in a unified way such ...
The average wind velocity (speed and direction accounted for) at a height of10 meters above the ground. Note that this is a vector average (i.e., the wind direction is considered). What is the fastest wind in the universe? Astronomers have discovered the fastest ultraviolet winds ever recor...
Furthermore, spatial distribution of flow velocity and pressure in the chamber was studied and the assumptions in traditional theoretical method were examined. Conclusion CFD simulation method avoids the dependency on test data and objectivity of parameter selection of traditional analytical methods. This ...
To further investigate the energy sink associated with the “IW killing” at super-inertial frequencies (>1.74×10−5 cps), which are mostly dominated by tidal frequencies, we compute the corresponding wind power u′⋅ττ′¯, where u is the surface horizontal velocity vector and ττ ...
Supported by magnetic pressure, the density of hot bubbles can be kept low to reduce the radiative cooling and to maintain the high temperature long time. Even in the stars redward of the dividing line, hot bubbles intermittently exist, and they can be sources of UV/soft X-ray emissions ...
andvavgis the average wind velocity. Both σ andvavgare taken over a predefined time period in order to maintain all measurements consistent. While this formula does a reasonable job at modeling the intensity of turbulence, it does not satisfy as an accurate predictor of when a major wind gust...
