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…
Gibbsian Hypothesis in Turbulence
G. L. Eyink, S. Chen, Q. Chen
We show that Kolmogorov multipliers in turbulence cannot be statistically independent of others at adjacent scales (or even a finite range apart) by numerical simulation of a shell…
Athermodynamic Alignment in the Two-Dimensional Enstrophy Cascade
Xin Wang, Shiyi Chen, Robert E. Ecke +1
We study inertial-range statistics in the direct enstrophy cascade of two-dimensional turbulence via a numerical simulation of the forced Navier-Stokes equation. In particular, we…
Shock-Like Dynamics of Inelastic Gases
E. Ben-Naim, S. Y. Chen, G. D. Doolen +1
We provide a simple physical picture which suggests that the asymptotic dynamics of inelastic gases in one dimension is independent of the degree of inelasticity. Statistical chara…
Intermittency corrections to the mean square particle acceleration in high Reynolds number turbulence
Mark Nelkin, Shiyi Chen
The mean square particle acceleration in high Reynolds number turbulence is dominated by the mean square pressure gradient. Recent experiments by Voth et al [Phys. Fluids {\bf 10},…
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…
