Plasma simulation

Ion wind from a sDBD

The ion wind from an sDBD has been calculated by nonPDPSIM. Even after the end of the streamer propagation the ion wind does not vansih completely during the relaxation of the system.

Plasma Chemistry

Gas Conversion in a sDBD

Surface 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.

Plasma Bullet Jet

A plasma bullet jet is developed to monitor post-plasma catalysis mechanisms. A series of ICCD images shows how the plasma expands from a capillary to a substrate surface over 1.5 microseconds.
