Abstract
We theoretically study the flows of jammed frictionlessu granular materials driven by an external force between parallel plates. Using a continuum model, we analytically derive a scaling law that characterizes the critical behavior of the mass flux. When the external force is below a critical threshold, the mass flux remains zero, while it increases above this threshold, following a power-law dependence on the distance from the critical point. This scaling law is numerically verified using the discrete element method.
