This formula is used to estimate wind pressure wind speed of the general formula. It should be noted that the severity of air and acceleration of gravity vary with latitude and altitude. In general, r / g is less on the plateau than in the plains, which means that the same wind speed ...
Wind tunnelforce testpressure testflying wingUsually, force tests and pressure tests are conducted with different model in wind tunnel which could cause trouble for aircraft design as the pressure test results always could not match the force test results. So attempts to do force tests along with...
Various forms of the equation relating radial wind speed to the central pressure by assumption of a cyclostrophic flow in TC has being employed to obtain one of these values when the other is known. Dvorak's technique that uses typical storm structures from satellite imagery has being ...
Atmospheric pressure and wind speed display device for security of e.g. ship, has frame with push buttons permitting to control preprogrammed functions of ... The device has a frame (1), control buttons (3), a pressure sensor and a programmed electronic device for converting initial data ...

Whatever the usage of the screens was, it was necessary to have good knowledge of how much the screen caused a pressure drop for wind speeds when analyzing both the inner thermal-flow distribution in the facility and the effect of reducing wind speed by using CFD. Furthermore, as for wind...
Examination of the Influence of Flow Speed on the Coherence Lengths in Turbulent Boundary Layers at High Subsonic Mach Numbers Wind tunnel measurements of wall pressure fluctuation were conducted at high subsonic Mach number. The data was analyzed in order to calculate the spatial ... S Haxter,K...
