A new ghost cell/level set method for moving boundary problems:application to tumor growth [PDF]

open access: yes, 2008
In this paper, we present a ghost cell/level set method for the evolution of interfaces whose normal velocity depend upon the solutions of linear and nonlinear quasi-steady reaction-diffusion equations with curvature-dependent boundary conditions.

Analytical Solution for Rheological Consolidation of Soft Clay with Threshold Hydraulic Gradient

open access: yes工程科学与技术, 2019
The influence of a threshold gradient of water flow in soft clays on consolidation behavior has been gradually recognized. However, the consolidation theory with consideration of a threshold hydraulic gradient and rheological characteristics has rarely ...

One dimensional parabolic free boundary problems

open access: yes, 1975
The method of lines is used to approximate explicit and implicit free boundary problems for a linear one dimensional diffusion equation with a sequence of free boundary problems for ordinary differential equations.

A comparative study of immersed-boundary interpolation methods for a flow around a stationary cylinder at low Reynolds number [PDF]

open access: yes, 2013
The accuracy and computational efficiency of various interpolation methods for the implementation of non grid-confirming boundaries is assessed. The aim of the research is to select an interpolation method that is both efficient and sufficiently accurate

Implementation and Validation of Explicit Immersed Boundary Method and Lattice Boltzmann Flux Solver in OpenFOAM

open access: yesDynamics
In this work, the explicit boundary-condition-enforced immersed boundary method (EIBM) and the lattice Boltzmann flux solver (LBFS) are integrated into OpenFOAM to efficiently solve incompressible flows with complex geometries and moving boundaries.

Optimal control of a moving boundary by laser heating in a 2-phase Stefan problem

open access: yes, 2008
The 2-phase heat control problem by a single laser point input is studied and a method of overcoming the moving boundary problem is introduced. This is achieved by applying a sequence of linear time varying control problems which converge to the single ...
