A multiscale numerical technique for the simulation of partial discharges

In questo lavoro si tratta la soluzione numerica di un modello di scariche parziali interamente basato sulla soluzione di un set di equazioni differenziali.

The partial discharge (PD) phenomenon can be modeled as the interaction of a solid insulating surface with a cold discharge in a void filled with gas. While there are many examples of simulations of cold discharges in gases, the dynamics of partial discharges is often treated in a semi-empirical or simplified way. In this work we treat the development and the numerical solution of a model which is entirely based on a set of Partial Differential Equations (PDEs). A particular attention has been devoted to reduce the computational cost by using a hierarchy of models.
