Transition blocage/écoulement d'une suspension non brownienne dans un liquide

Abstract : We develop a study on the flow behavior in 2D rectangular section. Few experimental studies are carried out in the case of particles carried by a fluid. However, these flows are sharing similarities with experiences which the setting movement of particles depends solely on the gravitational force (Zuriguel 2003). However, the suspensions of the jamming phenomenon is not a systematic phenomenon. It will therefore be able to characterize the influence of parameters such as fluid-particle interfaces, dense flows, hydrodynamic forces. Here we present a model that describes the exponential distribution of blockages in the flow. Then we present an interpolation representing the evolution law of avalanche size by the ratio R.
