Numerical simulation of arc splitting process in a LV switching device considering thermo-field emission mechanism

The need for simulation of arc dynamics in a low voltage switching device has been widely felt in the industry. The movement of the arc plasma in the 3D model is governed by venting and magneto-hydrodynamic interaction. A Coupled Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) solver approach is adopted to enhance the accuracy of the solutions.
