Lattice Boltzmann simulations of three-dimensional drops spreading on a uniform solid surface will be discussed. It will be shown that, if the liquid–liquid interface is sufficiently thick, the contact line velocities obtained from the simulations agree well with theoretical predictions based...

For interface-tracking simulation of two-phase flows with a high density ratio, we propose a computational method, NS–PFM, combining Navier–Stokes (NS) equations with phase-field model (PFM) based on the free energy theory. Through the numerical simulations, it was confirmed that (1) the...

A new thermal entropic lattice Boltzmann model on the standard two-dimensional nine-velocity lattice is introduced for simulation of weakly compressible flows. The new model covers a wider range of flows than the standard isothermal model on the same lattice, and is computationally efficient and...

The paper describes a new computational tool based on lattice Boltzmann methods for the simulation of two-phase flow and heat transfer phenomena in boiling water reactor fuel bundles.

Although diesel engines have an advantage of low fuel consumption in comparison with gasoline engines, several problems must be solved. One of the major concerns is that diesel exhaust gas has more particle matters (PM) including soot, which are suspected to be linked to human carcinogen. As one...

The results of a lattice Boltzmann simulation for collisions between two liquid drops in an immiscible liquid in a linear Stokes flow will be presented. The results will be compared with existing experimental results and asymptotic solutions. The mixing of a contaminant that is initially...
