On the Nonsymmetric Coupling Method for Parabolic-Elliptic Interface Problems [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2018
We consider the numerical approximation of parabolic-elliptic interface problems by the non-symmetric coupling method of MacCamy and Suri [Quart. Appl. Math., 44 (1987), pp. 675--690]. We establish well-posedness of this formulation for problems with non-smooth interfaces and prove quasi-optimality for a class of conforming Galerkin approximations in ...

Weak and Classical Solutions to Multispecies Advection–Dispersion Equations in Multilayer Porous Media

open access: yesMathematics, 2023
The basic model motivating this work is that of contaminant transport in the Earth’s subsurface, which contains layers in which analytical and semi-analytical solutions of the corresponding advection–dispersion equations could be derived. Then, using the

Reaction of the preloaded rotation shell with the rigid nose part of the apparatus to a shock wave in the liquid

open access: yesНаучный вестник МГТУ ГА, 2021
The article investigates the problem of hydro-elastic interaction of a weak shock wave with a rigid nosed rotation shell preloaded with axial forces. The shell is enclosed in a rigid parabolic screen, i.e.

A numerical method for a stefan-type problem

open access: yesMathematical Modelling and Analysis, 2011
A Stefan-type problem is considered. This is an initial-boundary value problem on a composite domain for a parabolic reaction-diffusion equation with a moving interface boundary.

Anomalous Dynamics of Recalescence Front in Crystal Growth Processes: Theoretical Background

open access: yesCrystals, 2022
A theory for crystal nucleation and growth with the recalescence front is developed. The theory is based on the saddle-point technique for evaluating a Laplace-type integral as well as the small parameter method for solving the moving boundary heat ...

Mathematical Modeling of the Solid–Liquid Interface Propagation by the Boundary Integral Method with Nonlinear Liquidus Equation and Atomic Kinetics

open access: yesCrystals, 2022
In this paper, we derive the boundary integral equation (BIE), a single integrodifferential equation governing the evolutionary behavior of the interface function, paying special attention to the nonlinear liquidus equation and atomic kinetics.

Phase-Field Model of Cell Motility: Traveling Waves and Sharp Interface Limit [PDF]

open access: yes, 2016
This letter is concerned with asymptotic analysis of a PDE model for motility of a eukaryotic cell on a substrate. This model was introduced in [1], where it was shown numerically that it successfully reproduces experimentally observed phenomena of cell ...

Spherically symmetric solutions to a model for phase transitions driven by configurational forces [PDF]

open access: yes, 2011
We prove the global in time existence of spherically symmetric solutions to an initial-boundary value problem for a system of partial differential equations, which consists of the equations of linear elasticity and a nonlinear, non-uniformly parabolic ...
