Simulating multicomponent multiphase electrohydrodynamic flows using a hybrid pseudopotential lattice Boltzmann and finite difference model

Physical Review Research
Electrohydrodynamics (EHD) are widely utilized to manipulate fluid behaviors in practical applications, such as EHD high-resolution printing and EHD nebulization for producing monodispersed small droplets. In these applications, multicomponent multiphase

Equation of State’s Crossover Enhancement of Pseudopotential Lattice Boltzmann Modeling of CO₂ Flow in Homogeneous Porous Media

Fluids, 2021
The original Shan-Chen’s pseudopotential Lattice Boltzmann Model (LBM) has continuously evolved during the past two decades. However, despite its capability to simulate multiphase flows, the model still faces challenges when applied to multicomponent ...

Numerical models for ground deformation and gravity changes during volcanic unrest: simulating the hydrothermal system dynamics of a restless caldera [PDF]

Solid Earth, 2016
Ground deformation and gravity changes in restless calderas during periods of unrest can signal an impending eruption and thus must be correctly interpreted for hazard evaluation.

A new lattice Boltzmann model for interface reactions between immiscible fluids [PDF]

, 2015
In this paper, we describe a lattice Boltzmann model to simulate chemical reactions taking place at the interface between two immiscible fluids. The phase-field approach is used to identify the interface and its orientation, the concentration of reactant

Recent advances in the simulation of particle-laden flows [PDF]

, 2014
A substantial number of algorithms exists for the simulation of moving particles suspended in fluids. However, finding the best method to address a particular physical problem is often highly non-trivial and depends on the properties of the particles and
