Numerical simulation of the coaxial tube of dielectric barrier discharge

For researching the coaxial tube of the dielectric barrier discharge,the paper is based on one-dimensional fluid mechanics model and uses the Fortran program of tri-diagonal matrix chase-after method.Not only the time evolutions of the discharge current and gas voltage,but also the space and time distributions of the electric field and the electron,meta-stable state atom and ion densities are numerically calculated by solving the one-dimensional continuity and momentum equations for electrons and ions,coupled to the current continuity equation.The properties of the coaxial tube of dielectric barrier discharge under the conditions of different driving frequency,voltage or dielectric layer are also discussed and analyzed.
