Lattice Boltzmann method for the fractional advection-diffusion equation.
Mass transport, such as movement of phosphorus in soils and solutes in rivers, is a natural phenomenon and its study plays an important role in science and engineering. It is found that there are numerous practical diffusion phenomena that do not obey the classical advection-diffusion equation (ADE). Such diffusion is called abnormal or superdiffusion, and it is well described using a fractiona...
متن کاملAdvection-diffusion lattice Boltzmann scheme for hierarchical grids
In this paper we describe an extension of a recently developed lattice Boltzmann method for solving the advection–diffusion equation. Our proposed approach allows to couple grids of different grid resolutions and includes a staggered timestepping scheme, interpolations in space and time and finally a scaling step ensuring the continuity of the desired macroscopic quantities across the grid inte...

متن کاملAssessment of Particle-size and Temperature Effect of Nanofluid on Heat Transfer Adopting Lattice Boltzmann Model
The investigation of the effect of nanoparticles’ mean diameter and temperature of Al2O3–water nanofluid on velocity and energy field using the lattice Boltzmann method is the main objective of this study. The temperature of the vertical walls is considered constant at Tc and Th, respectively, while the up and the down horizontal surfaces are smooth a...
متن کاملA Spectral Element Discontinuous Galerkin Thermal lattice Boltzmann method for Conjugate Heat Transfer applications
We present a spectral-element discontinuous Galerkin thermal lattice Boltzmann method (SEDG-TLBM) for fluid-solid conjugate heat transfer applications. In this work, we revisit the discrete Boltzmann equation (DBE) for nearly incompressible flows and propose a numerical scheme for conjugate heat transfer applications on unstructured, non-uniform mesh distributions. We employ a double-distributi...
