The effect of the shape of the applied voltage waveform on the energy efficiency of reactive species generation is investigated in an atmospheric pressure RF microplasma jet operated in a He/O$_2$ mixture (99.5\%/0.5\%) based on a one-dimensional...
Hydrogen is often envisioned as a green fuel and energy carrier. However, a greenhouse gas-free production method is still needed for this purpose. A promising method is the pyrolysis of methane. Here, we present the 3-dimensional simulation of...
Magnitude of the electric field of the microwave plasma torch simulated with ansys HFSS
A uniform atmospheric pressure dielectric barrier discharge is operated in helium with an admixture (0.45%) of nitrogen. The discharge is ignited in the gas gap between a driven and a grounded electrode and propagates along the dielectric surface...
This work utilizes 1d3v Particle-in-Cell/Monte Carlo Collisions (PIC/MCC) simulations of a symmetric discharge in the low-pressure regime with the inclusion of realistic electron-surface interactions for silicon dioxide. A diagnostic framework is...
The present study investigates the physics of a nanosecond-pulsed microplasma operated at a pressure of 200 mbar with the help of a particle-in-cell simulation with Monte Carlo treatment of collision (PIC/MCC) and (semi-)analytical models. The...
A spatially two dimensional fluid-MC hybrid (fluid-kinetic) simulation method is developed and applied to the COST reference microplasma jet operated in helium with an oxygen admixture of 0.5\%, excited by a single frequency voltage waveform with...
A humid atmospheric pressure plasma jet was used to treat an aqueous liquid. The transport of hydrogen peroxide and hydroxyl from the plasma to the liquid was analyzed. Two in-situ liquid diagnostics for each species were compared and validated....
Characterisation of the vibrational kinetics in nitrogen-based plasmas at atmospheric pressure is crucial for understanding the wider plasma chemistry, which is important for a variety of biomedical, agricultural and chemical processing...
With the increasing demands towards large area plasma etching and deposition, the radial uniformity of capacitively coupled plasmas (CCPs) becomes one of the key factors that determine process performance in industrial applications. However,...
