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 ...
Simulation results and applications of an advection bounded scheme to practical flows
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2012-01-01)
This paper reports experiments on the use of a recently introduced advection bounded upwinding scheme, namely TOPUS (Computers & Fluids 57 (2012) 208-224), for flows of practical interest. The numerical results are compared ...
Backward adaptive brightness temperature threshold technique (BAB3T): A methodology to determine extreme convective initiation regions using satellite infrared imagery
(Molecular Diversity Preservation International, 2020-01)
Thunderstorms in southeastern South America (SESA) stand out in satellite observations as being among the strongest on Earth in terms of satellite-based convective proxies, such as lightning flash rate per storm, the ...
A convective model for light curves of ZZ Ceti Stars
(ASP Astronomical Society of the Pacific, 2005-06)
The erratic behavior of the luminosity in ZZ Ceti light curves may be explained in terms of the sum of several convective fluctuations, where the heat flux is propagated in time by thermal waves. We present simulations of ...
Implementation of convective heating in Companhia Siderúrgica Nacional Blast Furnace runners
(2013-01-21)
This paper describes the main characteristics and advantages of convective heating system for refractory lining, compared with conventional heating systems. In addition the main results obtained are presented with its ...

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; ...
