Lattice Boltzmann model for numerical relativity [PDF]

open access: yesPhysical Review E, 2016
In the Bona-Masso formulation, Einstein equations are written as a set of flux conservative first order hyperbolic equations that resemble fluid dynamics equations. Based on this formulation, we construct a lattice Boltzmann model for Numerical Relativity.

Lattice Boltzmann Method for the Generalized Black-Scholes Equation

open access: yesAdvances in Mathematical Physics, 2023
In this paper, an efficient lattice Boltzmann model for the generalized Black-Scholes equation governing option pricing is proposed. The Black-Scholes equation is firstly equivalently transformed into an initial value problem for a partial differential ...

Modeling of natural convection by lattice Boltzmann in a partially heated cavity [PDF]

open access: yesE3S Web of Conferences, 2023
This study introduces the lattice Boltzmann method for modeling natural convection in a partially heated square cavity filled with air for varying Rayleigh numbers. A temperature gradient affects the vertical walls, whereas the other walls are treated as

Matrix lattice Boltzmann reloaded [PDF]

open access: yes, 2011
The lattice Boltzmann equation has been introduced about twenty years ago as a new paradigm for computational fluid dynamics. In this paper, we revisit the main formulation of the lattice Boltzmann collision integral (matrix model) and introduce a new ...

Lattice Boltzmann model for thermal transpiration [PDF]

open access: yesPhysical Review E, 2009
The conventional Navier-Stokes-Fourier equations with no-slip boundary conditions are unable to capture the phenomenon of gas thermal transpiration. While kinetic approaches such as the direct simulation Monte Carlo method and direct solution of the Boltzmann equation can predict thermal transpiration, these methods are often beyond the reach of ...

Generalized lattice Boltzmann model for frosting [PDF]

open access: yesPhysical Review E, 2019
Frosting is a multiscale and multiphysics problem, which presents a significant challenge for numerical methods. In this study, a generalized lattice Boltzmann (LB) model is developed to simulate the frosting of humid air at representative elementary volume scale.

A thermal lattice Boltzmann model for micro/nano-flows [PDF]

open access: yes, 2008
The dynamic behavior of charged micro and nanofluids plays a crucial role in a large variety of industrial and biological processes. Such dynamic behavior is characterized by the simultaneous occurrence of several competing mechanisms, such as ...
