Résumé

Dielectric barrier discharge (DBD) based surface plasma actuators have been well studied as flow manipulation devices. However, there is a dearth of research on their application for convective heat transfer enhancement. The adoption of DBD actuators to such areas requires a detailed study on the thermal characteristics of the plasma discharge. The present study conducts infrared thermography measurements on the surface of a thick dielectric (2–4 mm) based DBD actuator and characterizes it against various electrical and geometrical parameters. The temperature distribution is also studied in relation to the regimes of the discharge cycle through comparison with intensified charge-coupled device (iCCD) imaging. Measurements are also conducted with thin cylindrical electrode (wire) based configurations to study the influence of streamer inhibition. Based on the observed experimental results, a hypothesis is proposed on the mechanism of dielectric heating and the relationship between dielectric surface temperature and gas temperature.
