## Abstract We present an implementation of Hysing's (__Int. J. Numer. Meth. Fluids__ 2006; **51**:659β672) semiβimplicit method for treating surface tension, for finite volume models of interfacial flows. Using this method, the surface tension timestep restriction, which is often very stringent, c
The paper considers a system of partial differential equations of convection dispersion type, modelling a stratified two-phase fluid flow. Local existence in time is proved for a sufficiently smooth initial data, given in the set of physically admissible states. 1998 B. G. Teubner Stuttgart-John Wi
In this paper a numerical procedure for simulating two-uid ows is presented. This procedure is based on the Volume of Fluid (VOF) method proposed by Hirt and Nichols 1 and the Continuum Surface Force (CSF) model developed by Brackbill et al. 2 In the VOF method uids of di erent properties are identi
