Abstract: Computational fluid dynamics simulations have been employed in many engineering applications to improve machines and processes. In this study, CFD is used to analyse the effect of geometrical modifications of a discharge chute in the performance of a drying process of silica (SiO2) and water (H2O) compound. Multi-phase flow simulations were carried on to study the gas-solid flow inside discharge chute to determine internal pressure, velocity and temperature of the flow. The results for the modified geometry show a reduction in the flow velocity and in the pressure that can increase the flow rate of the compound and reduce material’s sedimentation. The simple geometric modification of the discharge chute proposed in this study might reduce maintenance and lead to production efficiency gains.
