Detection and Estimation of Wake Vortex On

An algorithm for the detection and estimation of a wake vortex using a lateral Range Height Indicator (RHI) observation of a pulsedDoppler lidar is proposed. By estimating physical parameters from measured Doppler spectra, the proposed method achieves high accuracy and robustness even in low Carrierto-Noise Ratio (CNR) conditions. This paper describes the methodology and presents an initial eva...

Dynamic Load Alleviation in Wake Vortex Encounters

Longitudinal vortex structures in a cylinder wake

Recently, flow visualizations by Wei and Smith,’ Williamson,’ Welsh et a1.,3 and Bays-Muchmore and Ahmed4 have shown that three-dimensional (3-D) vertical structures develop in the wake of a bluff body. The 3-D vertical structures were found to include pairs of counterrotating longitudinal vortices superimposed on the nominally two-dimensional (2-D) Kirmin vortex street as speculated by Grant’ ...
