Abstract

Applicability of discrete vortex approximation was tested experimentally for four types of flow conditions; an oscillating airfoil, roll-up of wake vortex layer originated from an oscillating plate, an impulsively started flat plate with an angle-of-attack and a two-dimensional rotating elliptic airfoil. Detailed flow visualization reveals the mechanism of creation, growth and migration of vortices and the comparison with those predicted by discrete vortex method has been done. It is concluded that this numerical simulation method is most usefull to predict global feature of the flow fields and care must be taken not to excessively increase the spacial and time resolution.
