Adhesive particle flow : a discrete-element approach /
"A particulate flow is one in which a moving fluid interacts with a large number of discrete solid particles. The category is extraordinarily broad, encompassing everything from suspended dust carried by atmospheric winds to avalanches of debris or snow rolling down a hillside. Widely varying i...
