A magnetic field coupling lattice Boltzmann model and its application on the merging process of multiple-ferrofluid-droplet system

Xiang Li et al.

Summary: This study focuses on the dynamics of ferrofluid droplets in a Newtonian fluid, utilizing a magnetic field coupling lattice Boltzmann model to solve the incompressible Navier-Stokes equations and the Cahn-Hilliard equation. The addition of a mass-correcting term in the C-H equation enforces mass conservation, and the method is capable of simulating magnetic multiphase flows.

Influence of stagnant zones on solute transport in heterogeneous porous media at the pore scale

Chunwei Zhang et al.

Summary: Solute transport in porous media is sensitive to heterogeneity at all scales, with pore-scale behavior affecting larger scales. Using a lattice Boltzmann method, simulations show that more heterogeneous media exhibit larger dispersion coefficients, with distinctive time regimes and power-law scaling observed for different types of rocks. The significance of mass transfer rate on mechanical dispersion is evaluated using the Damhohler number.

Droplet impact of Newtonian fluids and blood on simple fabrics: Effect of fabric pore size and underlying substrate

T. C. de Goede et al.

Summary: When a droplet impacts a fabric mesh at high velocity, it spreads and penetrates the pores of the fabric. The reduced spreading ratio on fabrics is attributed to increased viscous losses during spreading, both with and without a substrate. Blood can be considered a Newtonian fluid when spreading on fabrics, similar to smooth surfaces.

Optimal surface-tension isotropy in the Rothman-Keller color-gradient lattice Boltzmann method for multiphase flow

Peter Mora et al.

Summary: By studying the accuracy of color-gradient calculations, optimal weights have been found to reduce anisotropic errors and improve the reliability of the method; the improved color-gradient calculation method can be more effectively applied to studies characterizing phenomenology and capillary processes.
