摘要：
We examine the validity of the time-dependent Ginzburg-Landau equation of granular fluids for a plane shear flow under the Lees-Edwards boundary condition derived from a weakly nonlinear analysis through the comparison with the result of discrete element method. We verify quantitative agreements in the time evolution of the area fraction and the velocity fields, and also find qualitative agreement in the granular temperature. (C) 2013 AIP Publishing LLC.
