Numerical simulation of a cold plasma jet for biomedical applications

Abstract

Throughout this paper, one of the most widely used plasma devices in biomedical applications, the Atmospheric Pressure Plasma Jet (APPJ), has been studied. We have numerically simulated an APPJ using a multifluid model that includes continuity equations for the species considered in the kinetic model, electron energy equation, Gauss’s law, and the gas thermal balance equation. After discretizing the equations using a control volume formulation, we developed a Fortran90 code to solve the resulting algebraic system using a modified strongly implicit procedure (MSIP) with a 5-point formulation based on the Lower-Upper (LU) factorization of the system matrix. Finally, temporal evolution was implemented using the Gauss- Seidel scheme.
