|Title:||Simulation of simple 2D plasma jet model for NO, OH, and H<inf>2</inf>O<inf>2</inf>production via Multiphysics in laminar flow and transport of diluted species through design of experiment method|
|Keywords:||Physics and Astronomy|
|Abstract:||The plasma jet technique, a popular method for generating reactive oxygen and nitrogen species through an inert gas (such as Ar) mixed with air, was investigated. A plasma jet model was developed from a selection of statistical data, and the resulting NO, OH, and H2O2 concentrations were examined. The objective of the study was to establish a simple 2D plasma jet module and to mathematically understand the involved chemical reactions through the Multiphysics (finite element method) program. Determination of optimized conditions via the design of experiment method was performed. To create new responses, three nominal concentrations (NO, OH, and H2O2) were used to measure the performance of the species product. A full factorial design based on two levels, or 23 runs, with three central points and two replications was employed in the simulations using COMSOL Multiphysics 5.3a software. The main effects and interactions between the variables were identified for three main parameters: gas velocities of 40-70 m/s, plasma gaps of 10-30 mm, and simulation times of 2.8-4 ms. These parameters were selected to unravel design possibilities with external variables, which can significantly contribute to the process of designing a prototype of a cell-scaled plasma jet model.|
