Collisional dissipation rate for binary mixtures of aspherical particles
نویسندگان
چکیده
The homogeneous cooling process of binary mixtures large aspherical particles and small spheres is modeled using DEM. dissipation rate increases with the increasing total solid volume fraction mixture. For a specified mixture, ratio in Energy equipartition analysis shows that translational rotational components granular temperature for are generally equivalent. also present between particles. Both particle aspect shape irregularity affect collisional rate. (AR) same shape. AR, more-irregular oval-like larger than less-irregular rod-like decreases sphericity.

Crystallization of hard aspherical particles.
We use numerical simulations to study the crystallization of monodisperse systems of hard aspherical particles. We find that particle shape and crystallizability can be easily related to each other when particles are characterized in terms of two simple and experimentally accessible order parameters: one based on the particle surface-to-volume ratio and the other on the angular distribution of ...
متن کاملOff-equilibrium fluctuation dissipation relation in binary mixtures
In this note we present numerical simulations of binary mixtures. We study the diffusion of particles and the response to an external driving force. We find evidence for the validity of the Cugliandolo Kurchan off-equilibrium fluctuation dissipation relation. The results are in agreement with the predictions of one step replica symmetry breaking and the dependance of the breakpoint parameter on...
متن کاملBinary Mixtures of Particles with Different Diffusivities Demix.
The influence of size differences, shape, mass, and persistent motion on phase separation in binary mixtures has been intensively studied. Here we focus on the exclusive role of diffusivity differences in binary mixtures of equal-sized particles. We find an effective attraction between the less diffusive particles, which are essentially caged in the surrounding species with the higher diffusion...
