Conservative local grid refinement for the vectorial lattice Boltzmann method
S. A. Hosseini, R. Strassle, I. V. Karlin
We present a conservative local grid-refinement coupling for the vectorial lattice Boltzmann method (VLBM), a kinetic-type scheme for hyperbolic conservation laws in which each con…
Effects of anisotropic confinement on droplet rebound from superhydrophobic surfaces
M. Feinberg, S. A. Hosseini, I. Karlin
On flat superhydrophobic surfaces, droplet rebound is well described by a single inertio-capillary time scale, yielding a contact-time that is independent of impact energy. This si…
Local kinetic sensors for adaptive mesh and algorithm refinement
R. M. Strässle, S. A. Hosseini, I. V. Karlin
This paper presents novel refinement sensors for the application to adaptive mesh and algorithm refinement (AMAR) with kinetic models, such as discrete velocity and lattice Boltzma…
Lattice Boltzmann model for non-ideal compressible fluid dynamics
S. A. Hosseini, M. Feinberg, I. V. Karlin
We present a new kinetic model and its lattice Boltzmann realization for the simulation of compressible, non-ideal fluid flows. The method employs first-neighbour lattices and intr…
Practical Kinetic Models for Dense Fluids
Ilya Karlin, Seyed Ali Hosseini
Nonlinear idempotent operator instead of a linear projection is introduced to derive kinetic models for dense fluids. A new lattice Boltzmann model for compressible two-phase flow…
Transition time of a bouncing drop
Yahua Liu, Seyed Ali Hosseini, Cong Liu +4
Contact time of bouncing drops is one of the most essential parameters to quantify the water-repellency of surfaces. Generally, the contact time on superhydrophobic surfaces is kno…
