Abstract :
This paper describes numerical simulations of two-phase electrohydrodynamics using a sharp-interface method. Simulations are performed on typical test cases from the literature, and the results are compared to methods that use a smeared interface. The results show that the sharp-interface method gives significant improvements in accuracy.
