Quantitative test of the time dependent Gintzburg-Landau equation for
sheared granular flow in two dimension
   [PDF]

Kuniyasu Saitoh, Hisao Hayakawa
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 vertical component to the sheared direction of the velocity field, and also found qualitative agreements in the velocity field in the sheared direction and the granular temperature.
