Abstract
In this study, a new approach to suppress wind-induced vibrations, "DBD plasma actuator", was investigated through wind tunnel experiments to determine its potential as a device for flow control around bridge deck sections. The purposes of this research were to confirm whether or not it would be possible to apply the plasma actuator as a countermeasure against wind-induced vibrations of bridge girders through the wind tunnel experiments in a low Reynolds number region, with its practical use in the future taken into consideration, and to understand the basic characteristics of the plasma actuator. Flow visualization was carried out for on and off controlled states of the plasma. As a result, it was found that the aerodynamic characteristics of a bridge deck section could be improved by utilizing a DBD plasma actuator.
