In this study, the pressure drop for the binary mixtures of particles differing in size and density in a pseudo-2D spouted bed was experimentally studied. A binary mixture of solid particles including sand, Gypsum, and polyurethane was used in the experimental setup. Effects of static bed height, cone angle, particles diameter, and a particles weight fraction on the bed pressure drop were e...

This paper investigates the long-term orbital stability of small bodies near the central binary of the Alpha Centauri system. Test particles on circular orbits are integrated in the field of this binary for 32 000 binary periods or approximately 2.5 Myr. In the region exterior to the binary, particles with semi-major axes less than roughly three times the binary’s semi-major axis ab are unstabl...

The implementation of solid colloidal particles suspended in a binary fluid mixture via the lattice Boltzmann method is described. To represent colloids in a binary mixture, boundary conditions for mass and momentum at the solid-fluid interface are extended to include a conserved compositional order parameter. The parallelisation of the fluid-particle problem is addressed, and its scaling inves...

Abstract Disordered packings of non-spherical particles and their mixtures are abundant in nature, but have so far attracted only few systematic studies. Previous investigations binary specific convex shapes established two generic properties: (i) the existence a unique density maximum when shape or mixture composition species varied; (ii) validity an ideal mixing law indicating that packing is...

This paper describes a concept of concentration and binary separation of particles and its experimental confirmations for digital microfluidics where droplets are driven by the mechanism of electrowetting-on-dielectric (EWOD). As a fundamental separation unit, a binary separation scheme is developed, separating two different types of particles in one droplet into two droplets, one type each. Th...
