N2 - This work evaluates the effectiveness of the Two-Fluid Model (TFM) to simulate gas flows with dense particles by using a simplified Fluidized Bed as a test case. The overarching objective is to check the prediction accuracy of the TFM Model. This document includes the simulations performed using two drag models, namely Gidaspow and Syamlal-O'Brien, using Ansys Fluent 18.1. The bubble evolution as well as the time-averaged volume-fraction distributions have been compared with prior simulations conducted using MFIX, Barracuda and also with experimental data found in literature. Though the low computational requirements and capability to produce reasonable time-averaged results makes TFM a better choice for industrial applications, the low prediction accuracy for the instantaneous quantities often renders it unsuitable for more scientifically demanding studies. Hence, this work aims at a critical evaluation of the TFM model for the specified test problem.
