A model of surface dielectric barrier discharge power

Surface dielectric barrier discharges (SDBDs) are a type of asymmetric discharge (DBD) that can be used to generate ions and produce aerodynamic forces in air. They have shown promise range aerospace applications, including as actuators for solid-state aircraft control or enhancement ion sources electroaerodynamic propulsion. However, their power draw characteristics not well understood. Whereas existing approaches use empirical functional fits estimate the specific SDBD configurations, we develop here physics-based model consumption accounts material geometric variation between SDBDs. The is based on models parallel-plate “volume” DBDs but “virtual electrode” resulting from changing plasma length particular We experimentally measure SDBDs three materials, eleven thicknesses, 29 electrical operating points find correlation with r2=0.99 (n?=?106) experiment. also measurements four experiments literature (n?=?101) our these experiments. Since do any measured parameters those model, this suggests has ability robustly predict different construction methods experimental techniques. Therefore, work provides robust method quantitative design optimization engineering
