Galilean invariance of lattice Boltzmann models
Xiaobo Nie, Xiaowen Shan, Chen Hudong
It is well-known that the original lattice Boltzmann (LB) equation deviates from the Navier-Stokes equations due to an unphysical velocity dependent viscosity. This unphysical depe…
Resolving singular forces in cavity flow: Multiscale modeling from atoms to millimeters
Xiaobo Nie, Mark. O. Robbins, Shiyi Chen
A multiscale approach for fluid flow is developed that retains an atomistic description in key regions. The method is applied to a classic problem where all scales contribute: The…
Dynamics of Freely Cooling Granular Gases
Xiaobo Nie, Eli Ben-Naim, Shiyi Chen
We study dynamics of freely cooling granular gases in two-dimensions using large-scale molecular dynamics simulations. We find that for dilute systems the typical kinetic energy de…
Dynamics of Vibrated Granular Monolayers
X. Nie, E. Ben-Naim, S. Y. Chen
We study statistical properties of vibrated granular monolayers using molecular dynamics simulations. We show that at high excitation strengths, the system is in a gas state, parti…
Lattice-Boltzmann Simulations of Fluid Flows in MEMS
Xiaobo Nie, Gary D. Doolen, Shiyi Chen
The lattice Boltzmann model is a simplified kinetic method based on the particle distribution function. We use this method to simulate problems in MEMS, in which the velocity slip…
Clustering Kinetics of Granular Media in Three Dimensions
Shiyi Chen, Yuefan Deng, Xiaobo Nie +1
Three-dimensional molecular dynamics simulations of dissipative particles (~ 10^6) are carried out for studying the clustering kinetics of granular media during cooling. The inter-…
