Abstract

This work aims to manipulate using plasma actuators a fully developed turbulent boundary layer over a flat plate, with a view to reduce the friction drag. Four different plasma actuator configurations were designed to generate streamwise vortices. While the time-resolved PIV was used to capture the development and interaction of streamwise vortices in a plane normal to the mean flow, a surface balance technique was deployed to measure the skin-friction drag. A new calibration method is proposed for this technique to resolve accurately the friction drag change. It has been found that the plasma-actuator-generated vortices and their interactions with the boundary layer may lead to a drag reduction up to 50%. The control efficiency is also estimated.
