Investigation on unsteady behavior of near-wake flow of a blunt-base body by an optical-flow algorithm
In this study, an optical-flow algorithm was applied to analyzing unsteady behavior of nearwake flow. The experiment was conducted at low-speed conditions and at Reynolds number around ReD = 1.97×104 to obtain image database for optical-flow processing. Measurement frequency was at 2000 fps.
