We study a reaction-diffusion system with moving boundary describing a prototypical fast reaction-diffusion scenario arising in the chemical corrosion of concrete-based materials. We prove the continuity with respect to data and parameters of weak solutions to the resulting moving-boundary system of partial differential equations.

OVING-BOUNDARY BLECTROPUORESIS is a widely used technic for the investigation of colloidal systems. A limitation of this method, however, is the considerable amount of time required for a single experiment. It is particularly time consuming where the accumulation of large amounts of data is necessary. Furthermore, in the majority of instruments only 1 experiment at a time, and usually a total o...

Anomalous diffusion can be characterized by a mean-squared displacement 〈x(2)(t)〉 that is proportional to t(α) where α≠1. A class of one-dimensional moving boundary problems is investigated that involves one or more regions governed by anomalous diffusion, specifically subdiffusion (α<1). A novel numerical method is developed to handle the moving interface as well as the singular history kernel...

We analyze the known moving boundary effects in plasma and briefly review a mechanism for particle acceleration through a plasma front. We then show how this mechanism may affect particles crossing the boundary of an expanding quark gluon plasma.

This paper develops a framework to include Dirichlet boundary conditions on a subset of the boundary which depends on time. In this model, the boundary conditions are weakly enforced with the help of a Lagrange multiplier method. In order to avoid that the ansatz space of the Lagrange multiplier depends on time, a bi-Lipschitz transformation, which maps a fixed interval onto the Dirichlet bound...

This paper presents the flow field analysis in the Puffer-tyep (P-T) circuit breakers. There are many problems in analyzing the flow field in circuit breakers such as shock wave, complex geometry, moving boundary and so on. For the cold gas analysis, the flow field computation for the high voltage gas blast circuit breaker with the moving boundary by meshfree (FGCBM) method[1,2] is employed to ...

Since 1970, a series of systematic investigations have been performed on three modes of moving reaction boundaries (MRBs), viz. moving precipitate boundary (MPB), moving neutralization boundary (MNB) and moving chelation boundary (MCB). So far, there has not been any review on them. Herein, we firstly review the MPB with respect to its velocity, product concentration, elution displacement, stac...
