Poisson-Boltzmann description of the electrical double layer including ion size effects
(American Chemical Society, 2011-12)
The electrical double layer is examined using a generalized Poisson-Boltzmann equation that takes into account the finite ion size by modeling the aqueous electrolyte solution as a suspension of polarizable insulating ...
Lattice-Boltzmann study of the wind- driven dynamics of shallow sea waterEmpleo de método de Lattice Boltzmann en el estudio de la dinámica de las aguas costeras como consecuencia del arrastre del viento
(Universidad de la Habana, 2018-05-06)
The Lattice-Boltzmann method is a powerful tool to simulate fluid dynamics in complex geometries. In this work, this algorithm is applied to the modeling of wind-driven flow of shallow sea water in interaction with the ...
Dimensionally regularized Boltzmann–Gibbs statistical mechanics and two-body Newton's gravitation
(Elsevier Science, 2018-08)
It is believed that the canonical gravitational partition function Z associated to the classical Boltzmann–Gibbs (BG) distribution [Formula presented] cannot be constructed because the integral needed for building up Z ...
Boltzmann or Gibbs Entropy?: Thermostatistics of Two Models with Few Particles
(Scientific Research, 2015-07-15)
We study the statistical mechanics of small clusters (N ~ 10 - 100) for two-level systems and harmonic oscillators. Both Boltzmann’s and Gibbs’s definitions of entropy are used. The properties of the studied systems are ...
An Improved Immersed-Boundary Algorithm for Fluid-Solid Interaction un Lattice-Boltzmann Simulations
(Planta Piloto de Ingeniería Química, 2013-08)
An improved algorithm combining the features of the lattice Boltzmann and the immersed-boundary methods is presented. Following previous formulations, the method represents a fluid con-strained by flexible boundaries by ...
Verlinde's conjecture in a Boltzmann-Gibbs relativistic frame
(Elsevier Science, 2019-08-01)
Verlinde’s conjecture (VC) that gravitation is an emerging entropic force has been proved in a classical, non relativistic context in Plastino and Rocca (2018). Here we demonstrate the VC’s validity in a special relativity ...
Measurement of atomic transition probabilities with laser-induced breakdown spectroscopy using the 3D Boltzmann plot method
(Pergamon-Elsevier Science Ltd, 2019-04)
This work presents a method for the determination of atomic transition probability of the emission lines of a given element using the 3D Boltzmann plot method. The method exploits the third (temporal) dimension of a classical ...
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 ...
A Python implementation in graphic processing unit of a lattice Boltzmann model for unstable three-dimensional flows in immersed permeable media
(American Institute of Physics, 2020-12)
The implementation of a lattice Boltzmann model for three-dimensional permeable media with localized drag forces is presented. The model was previously introduced for two-dimensional geometries and follows the basics of ...
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 ...
