Lattice Boltzmann methods for multiphase flow and phase-change heat transfer
TL;DR: A comprehensive review of the lattice Boltzmann (LB) method for thermofluids and energy applications, focusing on multiphase flows, thermal flows and thermal multi-phase flows with phase change, is provided in this paper.
Journal ArticleDOI
Lattice Boltzmann modeling of multiphase flows at large density ratio with an improved pseudopotential model.
TL;DR: The improved pseudopotential LB model is numerically validated via the simulations of stationary droplet and droplet oscillation and it is found that a lower liquid viscosity can be gained in the pseudopotentials model by increasing the kinematic viscosities ratio between the vapor and liquid phases.
Journal ArticleDOI
Symmetry breaking in drop bouncing on curved surfaces.
TL;DR: It is shown that a drop impinging on Echevaria leaves exhibits asymmetric bouncing dynamics with distinct spreading and retraction along two perpendicular directions, which results from an asymmetric momentum and mass distribution that allows for preferential fluid pumping around the drop rim.

Wetting: statics and dynamics
TL;DR: In this paper, the authors present an attempt towards a unified picture with special emphasis on certain features of "dry spreading": (a) the final state of a spreading droplet need not be a monomolecular film; (b) the spreading drop is surrounded by a precursor film, where most of the available free energy is spent; and (c) polymer melts may slip on the solid and belong to a separate dynamical class, conceptually related to the spreading of superfluids.

Critical point wetting
TL;DR: In this paper, it is shown that in any two-phase mixture of fluids near their critical point, contact angles against any third phase become zero in that one of the critical phases completely wets the third phase and excludes contact with the other critical phase.

Lattice Boltzmann model of immiscible fluids
TL;DR: A lattice Boltzmann model for simulating immiscible binary fluids in two dimensions is introduced and a theoretical value of the surface-tension coefficient is derived and found to be in excellent agreement with values obtained from simulations.
