Investigation of processes occurring in non-equilibrium plasma on interfaces between two phases with different permittivity and conductivity
Annotation in Czech
In this project we will address the theoretical and experimental issues relevant for nitrogen fixation driven by transient non-equilibrium streamer-spark plasmas on liquid-gas interface. This fundamental research is relevant for environment-friendly technologies aiming on replacement of industrially produced fertilizers. We will investigate both numerically and experimentally processes occurring under highly non-equilibrium conditions on interfaces between two phases with highly different permittivity and conductivity: humid air and water. Reaction kinetic model will be developed for: the gas phase including formation of active nitrogen species during streamer-spark transition, model for species transfer between gas and liquid and liquid phase transport and chemistry. Detailed advanced emission and laser-based diagnostics of streamer-spark discharge will be performed with high spatio-temporal resolution. Pump-probe technique will be used for determining highly transient species. Impedance characteristics will be measured by means of response of the liquid medium on Dirac-function.
