The Instability of a Four-Vortex Wake System in a Water Towing Tank

Abstract:

A simplified rectangular baseline-airfoil model attached with tailored flaps was designed to study the Rayleigh-Ludwieg instability by tailoring a four-vortex wake system. By means of PIV measurement in a water towing tank, the interaction process and circulation evolution of the wake system were obtained systematically. The circulation remains was reduced to ca. 40% after 43 wingspans which proved the application potentials of this method in alleviating the wake vortex.
