An Unusual Moving Boundary Condition Arising in Anomalous Diffusion Problems [PDF]

open access: yes, 1995
In the context of analyzing a new model for nonlinear diffusion in polymers, an unusual condition appears at the moving interface between the glassy and rubbery phases of the polymer.

Dual Solutions for Boundary Layer Flow of Moving Fluid over a Moving Surface with Power-Law Surface Temperature

open access: yesInternational Journal of Applied Mechanics and Engineering, 2013
An analysis of heat transfer for boundary layer forced convective flow past a moving flat surface parallel to a moving stream is presented. The power-law surface temperature at the boundary is prescribed.

Moving immersed boundary method [PDF]

open access: yesInternational Journal for Numerical Methods in Fluids, 2017
SummaryA novel implicit immersed boundary method of high accuracy and efficiency is presented for the simulation of incompressible viscous flow over complex stationary or moving solid boundaries. A boundary force is often introduced in many immersed boundary methods to mimic the presence of solid boundary, such that the overall simulation can be ...

A Unified Analytical Approach to Fixed and Moving Boundary Problems for the Heat Equation

open access: yesMathematics, 2021
Fixed and moving boundary problems for the one-dimensional heat equation are considered. A unified approach to solving such problems is proposed by embedding a given initial-boundary value problem into an appropriate initial value problem on the real ...
