Lin, Yi-hungAdomaitis, Raymond A.A global discretization approach was taken to solve a self- consistent DC glow discharge model to study the interplay between modeling assumptions and convergence of the numerical solution techniques. It was found that the assumed form of electron diffusivity temperature dependence had a profound influence on the computed solutions. The numerical techniques developed offer a simple to implement alternative for plasma model discretization.en-USmathematical modelingoptimizationsimulationcollocationcontinuationglobal basis functionsglow dischargeplasma processingpseudospectralintelligent control systemsTechnical Report
