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…
Integral balance methods applied to a non-classical Stefan problem
Julieta Bollati, Maria F. Natale, Jose A. Semitiel +1
In this paper we consider two different Stefan problems for a semi-infinite material for the non classical heat equation with a source which depends on the heat flux at the fixed f…
Exact solution for a two-phase Stefan problem with variable latent heat and a convective boundary condition at the fixed face
Julieta Bollati, Domingo A. Tarzia
Recently it was obtained in [Tarzia, Thermal Sci. 21A (2017) 1-11] for the classical two-phase Lamé-Clapeyron-Stefan problem an equivalence between the temperature and convective b…
Existence and uniqueness of the p-generalized modified error function
Julieta Bollati, María Fernanda Natale, José Abel Semitiel +1
In this paper, the p-generalized modified error function is defined as the solution to a non-linear ordinary differential problem of second order with a Robin type condition at x=0…
Heat balance integral methods applied to the one-phase Stefan problem with a convective boundary condition at the fixed face
Julieta Bollati, José A. Semitiel, Domingo A. Tarzia
In this paper we consider a one-dimensional one-phase Stefan problem corresponding to the solidification process of a semi-infinite material with a convective boundary condition at…
A New Mathematical Formulation for a Phase Change Problem with a Memory Flux
Sabrina Roscani, Julieta Bollati, Domingo Tarzia
A mathematical model for a one-phase change problem (particularly a Stefan problem) with a memory flux, is obtained. The hypothesis that the weighted sum of fluxes back in time is…
