Utilizing the L-PSJA for controlling cylindrical wake flow

Abstract

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 Kármán 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.
