Turbulent gas-solid flows in in-line tube banks are investigated using the two-fluid model in combination with a particle-wall collision model and generalised Eulerian particulate boundary conditions. Comparison of numerical prediction for one-way coupling is made with experimental data. The numerical predictions for two-phase flow in tube banks using two different turbulence model (the standard k-ε and RNG based k-ε turbulence models) are analysed. The effects of particle loading and particle size (i.e. particle inertia) on the gas flow properties in tube banks are studied by using a two-way coupling model.
