Suppression of the unsteady vortex wakes of a circular cylinder pair by a doubletlike counterrotation

abstract

• AbstractThe present investigation examines the suppression of unsteady, twodimensional wake instabilities of a pair of identical circular cylinders, placed sidebyside normal to freestream at a low Reynolds number of 150. It is found that when the cylinders are counterrotated, unsteady vortex wakes can be completely suppressed. At fast enough rotational speeds, a virtual elliptic body is produced by a closed streamline, strongly resembling a doublet potential flow. Copyright 2009 John Wiley & Sons, Ltd.
