000014081 520__ $$2eng$$aThe wavelengths and celerities of density waves in granular materials flowing down in a vertical tube are experimentally inves- tigated using spatiotemporal diagrams. The granular flow was filmed with a high-speed camera, and the diagrams were constructed by digital image processing, using a numerical code developed in the course of this work. Experimental results show the existence of two wave regimes. The first one is characterized by density waves with constant celerity, and the second one by periodic oscillations of the wave system.
