A smoothing technique for discrete delta functions with application to immersed boundary method in moving boundary simulations

Journal of Computational Physics, 2009
The effects of complex boundary conditions on flows are represented by a volume force in the immersed boundary methods. The problem with this representation is that the volume force exhibits non-physical oscillations in moving boundary simulations.

Moving social boundaries

Prosthetics & Orthotics International, 2008
There are many boundaries in society. There are geological boundaries, cultural boundaries, national boundaries and others. For persons with disabilities, there are other types of boundaries, such as physical, informational and social boundaries. They may be called barriers.

The Shape of a Moving Grain Boundary

Physica Status Solidi (a), 1972
An investigation was made of the shape of a bicrystal grain boundary in equilibrium and in motion under the action of a curvature (the free energy of the boundary) and of the difference of the surface energies of the grains. Proceeding from a quasi-equilibrium approximation, methods have been suggested for determining the parameters of a moving ...

Moving boundary “partition” electrophoresis

Analytical Biochemistry, 1971
Abstract 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, 1973
The 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 ...
