The paper considers corona discharge problems with multiple conductors, such as those appearing in some electrostatic precipitators. A common, precise condition is identified in which previous approaches proposed in literature fail. For dealing with these conditions, a novel formulation of the problem is proposed. Moreover, a Newton-Raphson scheme is defined for iteratively solving a non-standard Petrov-Galerkin Finite Element discretization of the problem. The presented approach is validated on a benchmark for which an analytical solution is known.

Abstract
The paper considers corona discharge problems with multiple conductors, such as those appearing in some electrostatic precipitators. A common, precise condition is identified in which previous approaches proposed in literature fail. For dealing with these conditions, a novel formulation of the problem is proposed. Moreover, a Newton-Raphson scheme is defined for iteratively solving a non-standard Petrov-Galerkin Finite Element discretization of the problem. The presented approach is validated on a benchmark for which an analytical solution is known.File in questo prodotto:
