This paper concerns the study of coupled effects electrohydrodynamic (EHD) and thermocapillary (TC) on dynamic behaviour a single liquid droplet. An incompressible Smoothed Particle Hydrodynamic (ISPH) multiphase model is used to simulate EHD-TC driven flows. The complex hydrodynamic interactions are modeled using continuum surface force (CSF) method, in which gradient interfacial tension Maran...

Abstract We comment on a recent article [Comput. Mech. 2020, 65, 487–502] about surface-tension modeling for free-surface flows with Smoothed Particle Hydrodynamics. The authors motivate part of their work related to novel principal curvature approximation by the wrong claim that classical formulation in SPH overestimates 3D factor 2. In this note we confirm correctness and point out misconcept...
