A3,A7 - Plasma ChemistryGas Conversion in an sDBDSurface Dielectric barrier discharges are perfect sources to allow for efficient mixing between plasma and gas. By using a fluid simulation and mimicking the plasma as a volume force acting on the gas, the trajectories of species can be modelled and followed in time. Publication:

A7 - sDBDSchlierenSchlieren imaging of the start phase of plasma-induced fluid flow in a microsecond-pulsed surface dielectric barrier discharge (SDBD) operated in air at 4 kHz, using a parallel grid line electrode configuration. The video visualizes the development of vortex structures and highlights the coupling between plasma streamers and the surrounding gas flow.

A5 - sDBDHe emissionTime-resolved electron impact excitation rate from the ground state into He I (3s)³S₁ near the grounded side of the SDBD, focused on a single electrode grid cell during a nanosecond-pulsed He/N₂ discharge at atmospheric pressure. The data is derived from phase-resolved optical emission measurements and captures the temporal evolution of excitation dynamics throughout the pulse. The video illustrates the formation and propagation of the ionization front.
