SUMMARY:Numerical Simulation of Partial Discharges in Electrical Treeing
DESCRIPTION:Beatrice Crippa (Politecnico di Milano), Andrea Villa (RSE), a
 nd Anna Scotti (Politecnico di Milano)\n\nElectrical Treeing is one of the
  main causes for the degradation of the insulating components of cables: p
 artial discharges occur in a gas-filled defect in the polymer under strong
  electrical fields.\nThis phenomenon can be modeled by a system of PDEs, d
 escribing the movement of charges in the defect and the evolution of the e
 lectrical field and potential in both the gas and the solid dielectric mat
 erial. However, the geometry of the defect makes the problem very challeng
 ing: such ramified subdomain with very small diameter can hardly be discre
 tized by a 3D mesh in realistic cases. To overcome this limitation we appr
 oximate the treeing as a one-dimensional graph, and derive a mixed-dimensi
 onal 3D-1D system of equations, reducing the problem complexity. The numer
 ical solution is based on Mixed FEM for the electrostatic problem and Fini
 te Volumes for the charges movement, and on a splitting to manage the mult
 iphysics coupling with reactive phenomena. The method is implemented in th
 e parallel C++ code Morgana.\n\nDomain: Computational Methods and Applied 
 Mathematics\n\nSession Chairs: Mauro Bianco (ETH Zurich / CSCS, ETH Zurich
 ) and Nur Aiman Fadel (ETH Zurich / CSCS)\n\n
