Calculation of wind separation process

Calculation of wind separation process

Calculation of the separation streamlines of barchans and ...

2005-11-1  The calculation of the stationary wind field is started by initializing the variables (e.g. the velocity to zero). Then the equations for the velocity, the pressure, the turbulent energy, and the turbulent dissipation are iteratively calculated. If this process converges the solution is attained after a certain number of steps.

NDBC - How are estimates of wind-seas and swell made

2010-2-8  Estimates of wind-sea and swell are made by selecting a separation frequency that partitions the wave spectrum into its wind-sea and swell parts. The respective parts of the spectrum are then used to compute significant wave height, peak frequency (or period), and mean direction of the swell and wind-seas portions of the spectrum.

2021-2-17  Surface friction tends to slow down wind passing over it. Wind speed is slowest at the surface and increases with height. For this reason anemometers are placed at a chosen standard height, i.e., 10 m in meteorology and 2 or 3 m in agrometeorology. For the calculation of evapotranspiration, wind speed measured at 2 m above the surface is required.

2021-11-19  In wind load, the main consideration is the comfort of people inside and outside of the buildings. Wind loads are initially horizontal in nature because of the movement of air relative to the earth. Wind load is required to be considered in design especially when the building exceeds two times the transverse dimensions to the exposed wind surface.
