Hybrid model simulations of He/O2 micro atmospheric pressure plasma jets
Abstract
We build a hybrid model to investigate the helium micro atmospheric pressure plasma jet with a small amount of oxygen admixture. The model treats electrons kinetically based on the Particle-in-cell/ Monte Carlo Collision (PIC/MCC) algorithm, while various heavy species based on the fluid equations. The simulation results show good agreements with multiple experimental diagnostics, including the electron heating dynamics, the helium metastable density, and the atomic oxygen density. We demonstrate that voltage waveform tailoring allows us to control and enhance the generation of reactive species, which are highly relevant for a variety of biological and technological applications.
