Summary:The plasma dynamics in a three-dimensional free-burning arc configuration are studied using an iterative hybrid finite-volume–finite-element scheme. In this scheme, Navier–Stokes equations are solved with a classical finite volume approach. It is a conservative method that is suitable for solving conservation equations. In addition, a nodal finite element analysis is used to solve Maxwell’s equations for the scalar and vector potentials. The finite-volume and finite-element modules are verified against well-known simple problems. The plasma is considered an incompressible fluid in chemical and thermal equilibrium or local thermodynamic equilibrium. The profiles of fluid and electromagnetic characteristics are depicted for a total current equal to 200 A. The results of this simulation method are in agreement with experimental and numerical predictions.
