Abstract 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.
