摘要: We present a hydrodynamic model that captures the essence of granular dynamics in vibrating bed. carry out linear stability analysis and uncover instability mechanism leads to appearance convective rolls via supercritical bifurcation bouncing solution. also explicitly determine onset convection as function control parameters confirm our picture by numerical simulations continuum equations.
