216104 Study on Fundamental Characteristics of DBD Plasma Actuator

Abstract

1 − 33 Yayoi − cho ， Inage ・ ku ， Chiba Drag reduction is a technical issue on the reduction of carborl dioxide gas emission ． Particularly ， DBD plasma actuator is a promising technology on active controt of the flow separation． In lhe present work ， efficiency of the plasma actUator is investigated experimentally for a varicty of parameters including dielectric materia1 ， thickness of the dielectric plate ， and gap between two clcctrodes ． It is found that ： ( a ) ethciency increases substantially with decreasing thickness of the dielectric plate ， however maximum value exists for the applied voltage ；( b ) as fbr materials ， efficiency of po 且 ytetrafluoroethylene ( PIFE ) is−400％ 1arger compared to polyoxybenzylmethyleng ］ ycolanhydride ( Bakelite ) ， Key 〃b7ぬ ： Plasma ActUator ， Dielectric Barrier Discharge ， Flow Contro1
