Stefan problems for the diffusion-convection equation with temperature-dependent thermal coefficients
Julieta Bollati, Adriana C. Briozzo
Different one-phase Stefan problems for a semi-infinite slab are considered, involving a moving phase change material as well as temperature dependent thermal coefficients. Existen…
Approximate solutions to one-phase Stefan-like problems with space-dependent latent heat
Julieta Bollati, Domingo A. Tarzia
The work in this paper concerns the study of different approximations for one-dimensional one-phase Stefan-like problems with a space-dependent latent heat. It is considered two di…
Approximate solutions to the one-phase Stefan problem with non-linear temperature-dependent thermal conductivity
Julieta Bollati, María F. Natale, José A. Semitiel +1
In this chapter we consider different approximations for the one-dimensional one-phase Stefan problem corresponding to the fusion process of a semi-infinite material with a tempera…
Existence and uniqueness of solution for two one-phase Stefan problems with variable thermal coefficients
Julieta Bollati, María Fernanda Natale, José Abel Semitiel +1
One dimensional Stefan problems for a semi-infinite material with temperature dependent thermal coefficients are considered. Existence and uniqueness of solution are obtained impos…
Explicit Solutions for Distributed, Boundary and Distributed-Boundary Elliptic Optimal Control Problems
Julieta Bollati, Claudia M. Gariboldi, Domingo A. Tarzia
We consider a steady-state heat conduction problem in a multidimensional bounded domain Omega for the Poisson equation with constant internal energy g and mixed boundary conditions…
One-phase Stefan-like problems with a latent heat depending on the position and velocity of the free boundary, and with Neumann or Robin boundary conditions at the fixed face
Julieta Bollati, Domingo A. Tarzia
In this paper, a one-phase Stefan-type problem for a semi-infinite material which has as its main feature a variable latent heat that depends on the power of the position and the v…
