Corona discharge is used in several applications such as surface treatment of polymers, photocopying or dust removal in air conditioning. Streamer formation is undesirable for most of these applications. Therefore, several studies have been dedicated to investigate the formation and propagation of streamers, which are still not fully understood. The most suitable models to describe streamers are hydrodynamic models, which are usually solved using the finite difference method.  In this paper we present the successful simulation of the formation and propagation of a streamer. This simulation is based on a two-dimensional hydrodynamic plasma model which has been solved by the finite element method using COMSOL Multiphysics®.
