%X Fluidized bed systems are widely used in chemical and process engineering due to their excellent heat and mass transfer properties. Numerical modeling plays a crucial role in understanding and optimizing these systems, with the Two-Fluid Model enhanced by the Kinetic Theory of Granular Flow (TFM-KTGF) and the coupled Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) approach emerging as leading techniques. This study employs both models to simulate gas-solid interactions and evaluates their performance using a benchmark single-spout fluidized bed case validated against experimental data. Subsequently, the influence of particle presence on gas flow distribution through a non-uniform distribution plate is analyzed. The results show that the common assumption of proportional flow distribution based on the opening area fraction is inaccurate, especially in the presence of particles. Both numerical models demonstrate this behavior, with TFM-KTGF showing comparable trends to the coupled CFD-DEM approach but at significantly reduced computational costs. The findings highlight the importance of accounting for particle dynamics in distribution plate design and promote the TFM-KTGF approach as a promising alternative for large-scale simulations.
