Low-Speed Flow Control Using Dielectric Barrier Discharge (DBD)

摘要

DBDs were created in a quiescent environment, and particle image velocimetry (PIV) was used to obtain field measurements of velocity induced by the discharge. These PIV measurements included random phase measurements and measurements phase-locked to the DBD driving frequency. Instantaneous and average velocity distributions were used for flow analysis. In addition, the effects of buoyancy and large-scale background air movement around the test device were also evaluated and efforts to eliminate or minimize spurious results arising from either effect were made.
