Abstract

The workshop of “Technical Section on Plasma Actuators” was held in the Mechanical Engineering Congress in 2018 of JSME, and participants exchanged their opinions actively. Although over 20 years have passed since the basic idea of plasma actuators (PA) was presented by Roth et al. in 1998, various technical problems remain to be solved, such as induced flow acceleration, power consumption reduction, durability and safety. In Japan, “Technical Section on Plasma Actuators” has been active in Fluids Engineering Division (FED) of JSME since December 2013. In addition to an organized session and a workshop at the Mechanical Engineering Congress of JSME, symposiums have been held every fiscal year. For the next five years, this technical section provides opportunities not only to exchange the latest information on PA research, but also to share properties of common PA test pieces which can help the members to advance their own research.
