An Investigation of the Near-Wake Properties Associated with Periodic Vortex Shedding from Airfoils.
Abstract
An investigation of the near wake of airfoils with various trailing edge configurations including splitter plates reveals properties which are conducive to wake periodicity. The frequency of the shedding process is found to scale with the near wake momentum thickness and a wake velocity simply related to the base pressure coefficient. Computer results suggest that the frequency and bandwidth of the vortex shedding process can be predicted by a solution of the complete Orr-Sommerfeld equation. (Author)
