Description

Image

Based on experiments and simulations, the species transport in the COST reference plasma jet will be studied from the gas inlet through the active plasma region into the effluent in the presence of Voltage Waveform Tailoring (VWT) and customised boundary surfaces (materials + topology). The buildup of different neutral species along the direction of the gas flow will be quantified and understood as a basis for advanced plasma source design. Moreover, the plasma jet design will be modified by introducing a mesh into one of the electrodes and closing the original nozzle to make use of the unique features of VWT and structured electrodes to enhance the flux of selected neutral species into the effluent through the gridded electrode. Finally, the unique potential of VWT to tailor the Electron Energy Probability Function (EEPF) in combination with the new plasma source design will be used to enhance the synthesis of NH3 via cold non-equilibrium plasma catalysis by selectively exciting and dissociating nitrogen by electron impact.
