Computation of solid–liquid phase fronts in the sharp interface limit on fixed grids

HS Udaykumar, R Mittal, W Shyy - Journal of computational physics, 1999 - Elsevier
A finite-difference formulation is applied to track solid–liquid boundaries on a fixed
underlying grid. The interface is not of finite thickness but is treated as a discontinuity and is …

Phase-field model for Hele-Shaw flows with arbitrary viscosity contrast. I. Theoretical approach

fluids with arbitrary viscosity contrast in a rectangular Hele-Shaw cell. With asymptotic …

Analysis of stiffness in the immersed boundary method and implications for time-stepping schemes

JM Stockie, BR Wetton - Journal of Computational Physics, 1999 - Elsevier
The immersed boundary method is known to exhibit a high degree of numerical stiffness
associated with the interaction of immersed elastic fibres with the surrounding fluid. We …

A pseudospectral procedure for the solution of nonlinear wave equations with examples from free-surface flows

PA Milewski, EG Tabak - SIAM journal on scientific computing, 1999 - SIAM
An algorithm for the solution of general isotropic nonlinear wave equations is presented. The
algorithm is based on a symmetric factorization of the linear part of the wave operator …

Dynamic generation of capillary waves

HD Ceniceros, TY Hou - Physics of fluids, 1999 - pubs.aip.org
We investigate the dynamic generation of capillary waves in two-dimensional, inviscid, and
irrotational water waves with surface tension. It is well known that short capillary waves …

Viscous fingering in magnetic fluids: numerical simulation of radial Hele–Shaw flow

I Drikis, A Cebers - Journal of magnetism and magnetic materials, 1999 - Elsevier
In this paper, the viscous fingering phenomena of the magnetic liquids in the case when the
magnetic field is applied normally to the Hele–Shaw cell is investigated by the numerical …
