The primary aim of this work is to create a computational model capable to describe chemical processes induced by a relatively new type of discharge named transient spark (TS). TS is a DC driven pulsed atmospheric pressure discharge with high repetition frequency (~ kHz) of short (~100 ns) high current pulses (~A). It was already applied for various environmental and biological applications. One part of this work will be related to the development of computational package for the calculation the evolution of concentration of plasma species, taking into account the pulse character of TS. Developed package is based on available open source ZDPlaskin libraries. Another part of this work will be associated with development of a physical model describing time evolution of reduced electric field strength (E/N) in TS. For this purpose we will use Open Foam, a open source multi physical modeling platform. It will be used for simulation of hydrodynamic effects involved in TS, namely during the streamer-to-spark transition phase. The results of the whole model will be compared with experimental data, obtained mainly by time resolved optical emission spectroscopy. Thus we can evaluate the model.
