Using intensified charge-coupled device imaging and phase-resolved optical emission spectroscopy, supported by two- dimensional plasma\u2013fluid simulations, the influence of oxygen content, pressure, and pulse characteristics on streamer formation and propagation is systematically examined. The ls-pulsed discharge exhibits strongly stochastic, filamentary behavior, whereas the ns-pulsed discharge is more reproducible and suitable for phase-resolved analysis, while still exhibiting some localized filamentation, particularly for positive streamers. Lowering the oxygen content at fixed pressure mainly enhances positive-streamer propagation, while negative streamers are only weakly affected. Decreasing the pressure, in contrast, leads to longer propagation for both polarities and stronger streamer\u2013streamer interaction. The simulations reproduce the qualitative pressure scaling, but they overestimate streamer velocities, predict earlier inception, and indicate that the modeled discharge extinguishes before the applied voltage pulse has fully decayed, suggesting that surface-charge accumulation, pulse-to-pulse memory, and three-dimensional effects are required for quantitative agreement.\u003C\/p\u003E\n","url":"https:\/\/rdpcidat.rub.de\/dataset\/effects-pressure-and-oxygennitrogen-gas-mixture-streamer-formation-and-propagation-%C2%B5sns","state":"Active","log_message":"Edited by IKorolov.","private":true,"revision_timestamp":"Wed, 03\/11\/2026 - 08:14","metadata_created":"Tue, 03\/10\/2026 - 14:27","metadata_modified":"Wed, 03\/11\/2026 - 08:14","creator_user_id":"2fa50069-3923-4774-ad70-7f98bd94212e","type":"Dataset","resources":[{"id":"ee139da0-ded4-4513-b9e9-0154a67801fe","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/Data_repository_synthair_paper_2025.zip","description":"","format":"zip","state":"Active","revision_timestamp":"Wed, 03\/11\/2026 - 08:15","name":"Raw data for: Effects of pressure and oxygen\/nitrogen gas mixture on streamer formation and propagation in a \u03bcs\/ns-pulsed surface dielectric barrier discharge","mimetype":"application\/zip","size":"15.65 MB","created":"Tue, 03\/10\/2026 - 14:28","resource_group_id":"60dfa3fb-4113-4271-8531-8587fa07dcbe","last_modified":"Date changed  Wed, 03\/11\/2026 - 08:15"}],"tags":[{"id":"ec7dcc6e-8d82-4aa5-8f31-8ce85bd390b5","vocabulary_id":"2","name":"A5"},{"id":"6fb4f0e8-f239-47f1-9fef-1eb933f5195a","vocabulary_id":"2","name":"SDBD"},{"id":"2af5d325-26a2-40a8-b854-6a483281518e","vocabulary_id":"2","name":"PROES"},{"id":"7d26cd04-5f55-4d74-a9e9-87aacc8261a0","vocabulary_id":"2","name":"NONPDPSIM"}],"groups":[{"description":"\u003Cp\u003EThe group \u0022Allgemeine Elektrotechnik und Plasmatechnik\u0022 at the faculty for engineering and information science.\u003C\/p\u003E\n","id":"60dfa3fb-4113-4271-8531-8587fa07dcbe","image_display_url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/AEPT2.png","title":"AEPT","name":"group\/aept"}]}]}
