It is well known that a special attention is necessary to infer process information of a spouted bed at full-column using data from semi-cylindrical vessels. In this work experimental data are obtained from a semi-cylindrical spouted bed for comparison with CFD simulations performed using a 3D simulation scheme. The purpose of this paper is to contribute on the discussing about the influence of the flat wall in the solid behaviour inside the semi-cylindrical vessel by comparing numerical results with experimental data. Simulated results of fountain height, spout diameter and particle velocities inside the bed are compared with image data obtained from a semi-cylindrical column. The simulations were accomplished using the commercial package FLUENT 6.3.26.
