Stefan problems for the diffusion-convection equation with temperature-dependent thermal coefficients
(Pergamon-Elsevier Science Ltd, 2021-09)
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. Existence of at least one similarity solution is ...
Relationship between Neumann solutions for two-phase Lamé-Clapeyron-Stefan problems with convective and temperature boundary conditions
(Vinca Inst Nuclear Sci, 2017-01)
We obtain for the two-phase Lamé-Clapeyron-Stefan problem for a semi-infinite material an equivalence between the temperature and convective boundary conditions at the fixed face in the case that an inequality for the ...
Monitoring the convection coefficient in fermentative processes using numerical methods
(2018-05-01)
This work is based on the importance of monitoring the thermodynamic variables of sugarcane juice fermentation by Saccharomyces cerevisiae, using a numerical technique, and providing artifices that lead to the best performance ...
A free boundary problem for a diffusion–convection equation
(Pergamon-Elsevier Science Ltd, 2020-04)
One-dimensional free boundary problem for a nonlinear diffusion - convection equation with a Dirichlet condition at fixed face x=0, variable in time, is considered. Throught several transformations the problem is reduced ...
An anisotropic a priori error analysis for a convection-dominated diffusion problem using the HDG method
(Elsevier Science SA, 2019-03-01)
This paper deals with the a priori error analysis for a convection-dominated diffusion 2D problem, when applying the HDG method on a family of anisotropic triangulations. It is known that in this case, boundary or interior ...
Three-dimensional solidification with two possible crystallization states: Existence of solutions with flow in the melt

Assessment of a high-order finite difference upwind scheme for the simulation of convection-diffusion problems
(John Wiley & Sons Ltd, 2009-05-10)
This article deals with the Study of the development and application of the high-order upwind ADBQUICKEST scheme, an adaptative bounded version of the QUICKEST for unsteady problems (Commun. Numer Meth. Engng 2007; ...
Exact solution for a two-phase Stefan problem with variable latent heat and a convective boundary condition at the fixed face
(Birkhauser Verlag Ag, 2018-03-02)
Recently, in Tarzia (Thermal Sci 21A:1–11, 2017) for the classical two-phase Lamé–Clapeyron–Stefan problem an equivalence between the temperature and convective boundary conditions at the fixed face under a certain restriction ...
