Conservative multigrid methods for Cahn-Hilliard fluids
TL;DR: A conservative, second-order accurate fully implicit discretization of the Navier-Stokes and Cahn-Hilliard system that has an associated discrete energy functional is developed and convergence of the scheme numerically in both the presence and absence of flow is demonstrated.
Journal ArticleDOI
Interior Regularity Criteria for Suitable Weak Solutions of the Navier-Stokes Equations
TL;DR: In this article, interior regularity criteria for suitable weak solutions of the Navier-Stokes equations are presented. But they do not address the problem of finding a weak solution that is regular near an interior point z.
Journal ArticleDOI
Conservative multigrid methods for ternary cahn-hilliard systems ∗
TL;DR: A conservative, second order accurate fully implicit discretization of ternary (three-phase) Cahn-Hilliard (CH) systems that has an associated discrete energy functional and a nonlinear multigrid method to efficiently solve the discrete system at the implicit time-level.
Journal ArticleDOI
Global Solutions of Nonlinear Transport Equations for Chemosensitive Movement
TL;DR: This paper discusses kinetic models for chemosensitive movement, which also takes into account evaluations of gradient fields of chemical stimuli which subsequently influence the motion of the respective microbiological species.
Journal ArticleDOI
Regularity criteria for suitable weak solutions of the Navier-Stokes equations near the boundary ✩
TL;DR: In this paper, the Navier-Stokes equations near the boundary in dimension three were studied and it was shown that suitable weak solutions are continuous up to the boundary provided that the scaled mixed norm L x, t p, q with 3 / p + 2 / q ⩽ 2, 2 q ⊆ ∞, ( p, q ) ≠ ( 3 / 2, ∞ ) is small near the boundaries.
