Special Issue Information

Dear Colleagues,

In the last three decades, dielectric barrier discharge (DBD) plasma actuators have received widespread attention as novel flow control devices, with the advantages of a quick response and easy installation. The continued development of plasma actuators is expected. We invite you to contribute your research to this Special Issue. The aim of this Special Issue is to provide the reader with research on the performance evaluation, modeling, and application of conventional and innovative plasma actuators in flow control, including, but not limited to, the following issues:

  • The performance improvement of DBD plasma actuators;
  • The plasma physics of DBD plasma actuators;
  • The detailed performance evaluation of DBD plasma actuators;
  • New ideas and devices for efficiently driving DBD plasma actuators, including improvements in materials composing plasma actuators and power supply units;
  • DBD plasma actuators applied to control the flow around objects, such as airfoil, wings, blunt bodies, and fluid machines;
  • The side effects of actuation of plasma actuators, such as ozone and radio emissions, or the degradation of plasma actuator material due to continuous use.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Aerospace is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this study, a disk-type bluff body was installed at the upper part of a nozzle exit, and the circular jet inside the nozzle was controlled using a dielectric barrier discharge (DBD) plasma actuator (DBD-PA). The effects of the changes in the excitation frequency of the jet induced by the DBD-PA on the jet diffusion were elucidated. The experiments included visualization of the jet cross-section, particle image velocimetry analysis, and velocity measurements using an I-type hot-wire anemometer. When the DBD-PA was driven at a specific burst frequency (900–1400 Hz), a lock-in phenomenon occurred, in which the frequency of vortices generated in the initial jet coincided with the burst frequency. This lock-in phenomenon suppressed the merging of vortices by generating vortices at regular intervals. When vortex merging was suppressed, the jet was less likely to be entrained into the recirculation flow generated by the bluff body, thereby increasing the downstream jet width and average flow rate.
