Exact controllability for a string equation in domains with moving boundary in one dimension
Electronic Journal of Differential Equations, 2015 We consider a string equation in a domain with moving boundary. By using the multiplier method in non-cylindrical domains, we establish the exact boundary controllability in domains with moving boundary, and obtain a weaker condition on the time ...

Journal of Fluid Science and Technology, 2018 As an extension of the immersed boundary method with unified interpolation stencil (Kor, Badri Ghomizad, and Fukagata, J. Fluid Sci. Technol., Vol. 12, 2017, JFST0011), we propose an immersed boundary method that can handle moving boundary problems with ...

Particle creation by a moving boundary with a Robin boundary condition [PDF]
Journal of Physics A: Mathematical and General, 2006 We consider a massless scalar field in 1+1 dimensions satisfying a Robin boundary condition (BC) at a non-relativistic moving boundary. We derive a Bogoliubov transformation between input and output bosonic field operators, which allows us to calculate the spectral distribution of created particles. The cases of Dirichlet and Neumann BC may be obtained

A moving boundary model for fatigue corrosion cracking [PDF]
, 2003 Fatigue corrosion crack initiation and propagation is modelled as a moving boundary value problem. The model is based on three physical processes operating at the solid-environment interface – material dissolution, passive film formation and surface ...

Thermocapillary flow in a jet of liquid film painted on a moving boundary
, 2000 In the present paper, a liquid (or melt) film of relatively higher temperature ejected from a vessel and painted on the moving solid boundary is analyzed. The thermocapillary flow is driven by the temperature gradient on the free surface of a liquid film,

The onset of instability in unsteady boundary-layer separation
, 1996 The process of unsteady two-dimensional boundary-layer separation at high Reynolds number is considered. Solutions of the unsteady non-interactive boundary-layer equations are known to develop a generic separation singularity in regions where the ...

Учёные записки Казанского университета: Серия Физико-математические наукиA Stefan problem of heat transfer in semi-infinite bodies with an arbitrary number of unsteady moving boundaries during phase transitions was solved. Such problems arise when composite materials are heated at high temperatures, causing the binding agents

Moving Mesh Methods for Implicit Moving Boundary Problems [PDF]
, 2021 This talk will present a method for achieving arbitrarily high orders of accuracy when approximating PDE-based moving boundary problems using finite element (and related) methods on moving computational meshes. Its effectiveness will be demonstrated on a
