Abstract

In a number of industrial applications that include flow with dense solid particles, large solid objects are also existing in the flow. The behavior of large objects is complex due to the existence of interactions with surrounding gas/liquid flows, small particles and walls. In the case of fluidized and spouted beds, especially, it is still difficult to predict whether a solid object rises or sinks depending on its size, shape and density. In the present study, we try to develop a numerical model which reproduces the behavior of large solid object in a bubbling fluidized bed. Discrete element method (DEM) - Computational Fluid Dynamics (CFD) mesoscopic model is coupled with immersed boundary method (IBM).
