Purpose - The cylindrical wake flow is an important part of many engineering applications, including wake turbulence, acoustic noise, and lift/drag forces on bodies. The suppression of von Karman vortex street (VKS) is an important goal for flow control devices. The paper aims to discuss these issues.
Design/methodology/approach - The linear plasma synthetic jet actuator (L-PSJA) is utilized as a flow control device to suppress the VKS formation. Different configurations of the device is studied numerically.
Findings - Of the 12 configurations that were investigated, five configurations were able to suppress the formation of the VKS.
Originality/value - For the first time, the L-PSJA has been shown (through numerical simulations) to be able to suppress VKS.
