Abstract

In this paper, a high-order finite volume method is employed to solve the local energy
approximation model equations for a radio-frequency plasma discharge in a one-dimensional
geometry. The so called deferred correction technique, along with high-order
Lagrange polynomials, is used to calculate the convection and diffusion fluxes. Temporal
discretization is performed using backward difference schemes of first and second orders.
Extensive numerical experiments are carried out to evaluate the order and level of accuracy
as well as computational efficiency of the various methods implemented in the work.
These tests exhibit global convergence rate of up to fourth order for the spatial error, and of
up to second order for the temporal error.
