Moving boundary “partition” electrophoresis
Analytical Biochemistry, 1971Abstract The use of classical moving boundary electrophoresis in the study of biopolymers has decreased substantially in recent years. Among the reasons for its loss of popularity are the high cost of the equipment, the complexity of the technique, and the large amount of substance necessary for an analysis.

Boundary-Layer Separation From Downstream Moving Boundaries
Journal of Applied Mechanics, 1973The laminar boundary-layer equations for incompressible flow with a mild adverse pressure gradient were numerically solved for flows over downstream moving boundaries. It was demonstrated that the vanishing of skin friction in this case is not related to separation.2 Indeed the integration proceeds smoothly through a point of vanishing skin friction ...

Many engineering technologies involve the moving boundary problems for the radial seepage flow with a threshold pressure gradient, such as the well testing in the development of low-permeability reservoirs, heavy oil reservoirs and groundwater resources.

It is well known that the Non-Newtonian Bingham fluid flow in porous media does not obey the conventional linear Darcy’s law due to the yield stress for the Bingham fluid: There exists a threshold pressure gradient, which means that the seepage flow only

An improved immersed moving boundary for the coupled discrete element lattice Boltzmann method
Computers & Fluids, 2018In order to improve the accuracy of existing immersed moving boundary method (IMBM) for the coupled discrete element lattice Boltzmann method, a novel weighting function for the fluid-particle interfacial interactions in IMBM is presented in this work ...

A diffuse interface immersed boundary method for complex moving boundary problems
Journal of Computational Physics, 2018A diffuse interface immersed boundary method is proposed for problems with arbitrarily moving complex rigid bodies. The solid-fluid interface is replaced by fluid–fluid Lagrangian boundary. A universal equation that combines the momentum conservation and

Moving boundary electrophoretically mediated microanalysis
Journal of Chromatography A, 1996Moving boundary sample introduction is described as an alternative to zonal injection methods for the electrophoretically mediated microanalysis (EMMA) of leucine aminopeptidase (LAP). The capillary was initially filled with the analyte solution while the faster-migrating substrate, L-leucine-p-nitroanilide, was maintained in the inlet reservoir.

In this paper, we discuss a Stefan problem that includes a moving phase change material and a size-dependent thermal conductivity. This model also includes the time-dependent boundary condition at the first boundary, which later assumed as the periodic ...
