Abstract: Galerkin finite element methodology (with Q1Q0 elements) is used to quantify the effect of Coriolis force on multi-size slurry flow through rotating channels. A rotation- and concentration-modified κ–ε model is used for turbulence. The weak forms of the volume-averaged governing equations are solved using a multi-frontal solver combined with UMFPACK 4.4. For a rotation rate yielding a Coriolis acceleration equal to the gravitational acceleration, the trends of predicted results compare very well with published experimental results for a stationary horizontal channel (solids concentration of 12% by volume for six size classes with particle sizes in the range of 40–750 microns).
