Aplicação do método de lattice Boltzmann na simulação de meios filtrantes : implementação de códigos para geração do domínio de cálculo e condição de contorno de escorregamento
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2018-03-19)
Many studies have been carried out to find the best operating point for filter media, and the mathematical modeling and simulation are becoming a important tool. In this work, a code was built to generate geometric models ...
On the entropic derivation of the r−2 Newtonian gravity force
(Elsevier Science, 2018-09)
Following Verlinde's conjecture, we show that Tsallis’ classical free particle distribution at temperature T can generate Newton's gravitational force's r−2 distance's dependence. If we want to repeat the concomitant ...
Assessment of a double-MRT pseudopotential lattice Boltzmann model for multiphase flow and heat transfer simulations
(Elsevier, 2021-01)
In this work, a double-MRT lattice Boltzmann (LB) model for thermal multiphase flow is presented and analyzed. The model is based on a pseudopotential scheme, and introduces a second equation with a non-diagonal relaxation ...
A review of the classical canonical ensemble treatment of Newton's gravitation
(Molecular Diversity Preservation International, 2019-07)
It is common lore that the canonical gravitational partition function Z associated with the classical Boltzmann-Gibbs (BG) exponential distribution cannot be built up because of mathematical pitfalls. The integral needed ...
Caracterización del flujo a través de medios porosos usando el método de Lattice-BoltzmannCharacterization of the flow through porous media using the Lattice-Boltzmann method
(Asociación Física Argentina, 2009-01)
Se realizaron simulaciones del flujo a través de medios porosos 2D utilizando el método de Lattice-Boltzmann. Se estudió la relación que existe entre la porosidad y la permeabilidad, que son parámetros importantes para ...
A numerical study of two-particle settling in a thixotropic fluid using the immersed Boundary–Lattice Boltzmann method
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-02-05)
The settling of multiple particles in non-Newtonian fluids has great industrial importance. During the drilling operation in the oil and gas exploration, cuttings need to be removed from the borehole. The task is accomplished ...
Simulation of phase separation in a Van der Waals fluid under gravitational force with Lattice Boltzmann method
(Emerald, 2019-09)
Purpose – This paper aims to assess the accuracy of Lattice Boltzmann method (LBM) for numerical simulation of the stratification of a Van der Waals (VdW) fluid subjected to a gravity field and non-uniform temperature ...
