Structure of the Wake Behind an Airfoil
V. Uruba, P. Procházka, V. Skála
Abstract:
The wake behind an inclined plate simulating airfoil is to be studied experimentally. The vortical structures are identified eventually. Theirs topology and dynamical behaviour is to be studied in details using the Proper Orthogonal Decomposition method. The stereo time resolved Particle Image Velocimetry technique is used for the experimental research. The vortex trains with oblique orientation and chequered topology have been detected.
Keywords:
airfoil, boundary layer, wake, instability
