Aerodynamické síly, tlak a rychlost získané z vizualizace nestacionárního proudění kolem kmitajícího profilu-předběžné výsledky
Vlček, Václav ; Horáček, Jaromír
The contribution presents results of optical measurements of flow field around a self-oscillating double circle (DC)18% profile elastically supported in a measurement section of a wind tunnel. In a lower frequency range, the profile can vibrate like a dynamic system with two degrees of freedom with translation and rotation. The schlieren and interferometry methods were used for visualization of a two-dimensional flow in different phases of the profile motion. The total aerodynamic force, pressure and flow velocity on the profile surface were evaluated in given time instants.
