Coefficient of tangential restitution for non-spherical particles
Jana Wedel, Matjaž Hriberšek, Paul Steinmann, Jure Ravnik
Izvirni znanstveni članek
Oznake: nesferični delci;trki osnovnih delcev;tangencialni restitucijski koeficient;superelipsoidi;non-spherical particles;particle collision;tangential restitution coefficient;superellipsoids;
In various industrial and naturally occurring multiphase flows, whether dilute or dense, particle interaction plays a crucial role. In most cases, the particles are non-spherical, which poses a computational challenge in terms of particle motion and particle interaction, i.e. both particle–particle ...

Oznake: mehki delci;psevdotogo telo;baricenter;dinamika obliike;Lagrangevo sledenje delcev;soft particles;pseudo-rigid bodies;Barycenter and shape dynamics;Lagrangian particle tracking;
We propose a novel, demonstrably effective, utmost versatile and computationally highly efficient pseudo-rigid body approach for tracking the barycenter and shape dynamics of soft, i.e. nonlinearly deformable micro-particles dilutely suspended in viscous flow. Pseudo-rigid bodies are characterized b ...
