Abstract

The formation parameter concept has been applied to insects using simplifying assumptions, and subsequently used to describe the flow around a flat plate with a sinusoidal velocity profile. 1) The formation parameter was applied to 49 species of insect and was found to yield a formation number of roughly 4 when normalized by span instead of chord, indicating a preference for the spanwise direction in the importance of vortex formation in insects. Conclusions drawn from the parametric study require further investigation. 2) A DPIV study was conducted on the formation parameter for a stainless steel flat plate with a sinusoidal velocity profile. The formation number was found to be in the range of 0.5 to 1 for a flapping Reynolds number of 2300. Physical specifications of the flat plate were an aspect ratio of 6 and thickness to chord ratio of 3.125%.
