Vortex structures generated by dbd plasma actuator
Procházka, Pavel P.
This article deals with the research of vortex structures generated by a plasma actuator. Plasma actuators belong to devices that can be used for active flow control. Plasma actuator flow control has been in the center of interest for the last two decades. However, one can find only a limited amount of information dealing with the physical principal of this phenomenon. The conclusion of this article is formulated to give an explanation of physical laws acting during generating, evaluating and decay vortex structures in a complex way to ensure that results could be apply in the future for more applicable research.
Interakce UV záření s povrchovým nábojem v N2 povrchovém DBD
De Benedictis, S. ; Ambrico, P. F. ; Dilecce, G. ; Šimek, Milan
In this paper we report on space and time resolved spectroscopic measurements on Masuda type surface DBD fed by N2. In our configuration the discharge presents some defects that lead to the formation of some bright spot inside a regular discharge region formed by streamers. We have carried out an optical investigation of both the regular discharge region and the bright spot one with the aim to stress the aspects of photo emission contribution in the dynamics of microdischarge. We have carried out also spectroscopic space and time resolved investigation of discharge emission when UV photons by a pulsed laser interact with the dielectric surface of DBD. There is a similarity between the time evolution of emission from bright spots and that produced by laser photons.
