An Efficient Numerical Technique for the Simulation of Charge Transport in Polymeric Dielectrics

F Ragazzi, A Popoli, A Cristofolini - IEEE Access, 2024 - ieeexplore.ieee.org
In recent years, the use of HVDC cables has grown exponentially. One of the main
challenges that remains concerns the space charge accumulation inside the insulating …

[PDF][PDF] A quasi-2D approach for simulating corona discharges in air

The discharge model relies on the time-dependent drift-diffusion approximation. Each
plasma species' evolution follows the continuity equation:∂ n∂ t+∇· Γ= S.(1) Here, n is the …
