Dilute gas-solids systems are widely used as a proper reactor in many chemical, gas, food processing and waste treatment industries. The optimal utilization of this technology requires a good understanding of gas and particle flow patterns and the capability to predict such behavior. To respond to this need, the Two-Dimensional Steady State Two-Phase Hydrodynamic Model is developed to describe gas-solids flow behavior in dilute gas-solids flow systems. The model considers particles of same size and their boundary layers as a separate continuum phase. Furthermore, viscous dissipation forces and phase interaction forces are incorporated in the model. Numerical solution was obtained using the Method of Lines which is incorporated in FORSIM computer code. The predicted system variables agreed with the observed behavior of the experiments reported in the literature. The predicted average of the pressure drop profile using this model agreed well with the available experimental data in the literature.
