Wind shear climatology for large wind turbine generators [PDF]
, 1982 Climatological wind shear analyses relevant to the design and operation of multimegawatt wind turbines are provided. Insight is provided for relating the wind experienced by a rotating blade in a shear flow to the analysis results. A simple analysis of the wind experienced by a rotating blade for three types of wind shear profiles under steady-state ...

Meteorological tower wind shear characteristics, vertical wind speed profile, and surface roughness analysis near the coastline of Chennai [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2019 Extrapolation of wind data is required to estimate wind speeds at high altitudes. Doing so requires an essential understanding of wind shear characteristics related to the location or region.

Transient Flow Evolution of a Hypersonic Inlet/Isolator with Incoming Windshear
Aerospace, 2023 In this paper, a novel flow perturbation model meant to investigate the effects of incoming wind shear on a hypersonic inlet/isolator is presented. This research focuses on the transient shock/boundary layer interaction and shock train flow evolution in ...
