A comprehensive frictional-kinetic model for gas-particle flows: Analysis of fluidized and moving bed regimes

► The paper describes a comprehensive frictional-kinetic multi-fluid model. ► A μ(I)-rheology is used to close the frictional shear stresses. ► The model also accounts for dilation during frictional contacts under shear. ► The model shows excellent agreement with measurements in both regimes. ► The impact of the form of the solids wall shear stresses on the results is shown.
