Diffusion enhancement in a levitated droplet via oscillatory deformation
Yuki Koyano, Hiroyuki Kitahata, Koji Hasegawa +5
Recent experimental results indicate that mixing is enhanced by a reciprocal flow induced inside a levitated droplet with an oscillatory deformation [T. Watanabe et al. Sci. Rep. 8…
Lattice Boltzmann modeling and simulation of forced-convection boiling on a cylinder
Shimpei Saito, Alessandro De Rosis, Linlin Fei +4
When boiling occurs in a liquid flow field, the phenomenon is known as forced-convection boiling. We numerically investigate such a boiling system on a cylinder in a flow at a satu…
Color-gradient lattice Boltzmann model with nonorthogonal central moments: Hydrodynamic melt-jet breakup simulations
Shimpei Saito, Alessandro De Rosis, Alessio Festuccia +3
We develop a lattice Boltzmann (LB) model for immiscible two-phase flow simulations with central moments (CMs). This successfully combines a three-dimensional nonorthogonal CM-base…
Central-moments-based lattice Boltzmann scheme for coupled Cahn-Hilliard-Navier-Stokes equations
Alessandro De Rosis, Shimpei Saito, Akiko Kaneko +1
In this paper, we propose a lattice Boltzmann (LB) model to solve the coupled Cahn-Hilliard-Navier-Stokes equations. Differently from previous efforts, the LB equation for the flui…
