主 题：Sedimentation Brownian dynamics lattice Boltzmann method
摘 要：We investigate the sedimentation dynamics of a binary mixture,the species of which differ by their Stokes coefficients but are identical *** analyze the sedimentation dynamics and the morphology of the final deposits using Brownian dynamics simulations for mixtures with a range of sedimentation velocities of both *** addition,we use the lattice Boltzmann method to study hydrodynamic *** found a threshold in the difference of the sedimentation velocities above which the species in the final deposit are *** degree of segregation increases with the difference in the Stokes coefficients or the sedimentation velocities above the *** propose a simple analytical model that captures the main features of the simulated deposits.
