Nonlinear Two-Phase Stefan Problem [PDF]
Journal of Sciences, Islamic Republic of Iran, 2007 In this paper we consider a nonlinear two-phase Stefan problem in one-dimensional space. The problem is mapped into a nonlinear Volterra integral equation for the free boundary.

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017 We have studied the Stefan problem with Caputo fractional order time derivatives. The difference scheme is built. The algorithm and the program for a numerical solution of the Stefan problem with fractional differentiation operator are created.

The degenerate and non-degenerate Stefan problem with inhomogeneous and anisotropic Gibbs--Thomson law [PDF]
, 2010 The Stefan problem is coupled with a spatially inhomogeneous and anisotropic Gibbs-Thomson condition at the phase boundary. We show the long-time existence of weak solutions for the non-degenerate Stefan problem with a spatially inhomogeneous and ...

Supercooled Stefan problem with a Neumann type boundary condition
Electronic Journal of Differential Equations, 2020 We consider a supercooled one-dimensional Stefan problem with a Neumann boundary condition and a variable thermal diffusivity. We establish a necessary and sufficient condition for the heat flux at the fixed face x=0, in order to obtain existence ...

Scaling theory for two-dimensional single domain growth driven by attachment of diffusing adsorbates
New Journal of Physics, 2019 Epitaxial growth methods are a key technology used in producing large-area thin films on substrates but as a result of various factors controlling growth processes the rational optimization of growth conditions is rather difficult.
