Accurate wetting dynamics via a conservative Allen-Cahn based lattice Boltzmann approach for multiphase flows
Paolo Bello, Luca Mander, Marco Lauricella +3
In this work we propose a local geometric wetting boundary condition for a conservative Allen--Cahn-based lattice Boltzmann framework. The prescribed contact angle is imposed throu…
Negative quantum friction in nanoscale water flows: the Wigner picture
Adriano Tiribocchi, Marco Lauricella, Efthimios Kaxiras +1
We explore the phenomenon of "quantum" friction based on a single-particle model patterned after the Wigner equation describing electrons flow in a solid wall confining nanoscale w…
Three dimensional contractile droplet under confinement
Adriano Tiribocchi, Marco Lauricella, Andrea Montessori +1
We numerically study the dynamics of a three-dimensional contractile fluid droplet in the bulk and under confinement. We show that varying activity leads to a variety of shapes and…
Adaptive near-contact repulsion in conservative Allen-Cahn phase-field lattice Boltzmann multiphase model
Andrea Montessori, Maria Rosa Lisboa, Marco Lauricella +1
Unresolved thin-film dynamics often causes spurious coalescence in diffuse-interface simulations of multiphase flows. We address this issue by introducing a fully local repulsive n…
Ghost-Mode Filtered Fluctuating Lattice Boltzmann Method
Marco Lauricella, Andrea Montessori, Adriano Tiribocchi +1
Fluctuating lattice Boltzmann solvers are widely employed to model mesoscopic fluid behavior in soft-matter systems, including colloidal suspensions and dilute polymer solutions. D…
Regularized Fluctuating Lattice Boltzmann Model
Marco Lauricella, Andrea Montessori, Adriano Tiribocchi +1
We introduce a regularized fluctuating lattice Boltzmann model (Reg-FLBM) for the D3Q27 lattice, which incorporates thermal fluctuations through Hermite-based projections to ensure…
