Coupled RANS-LPT modelling of dilute, particle-laden flow in a duct with a 90° bend

► Full three-dimensional simulation and duct curvature effect on the multiphase flow. ► Full anisotropy of particle dispersion. ► Investigation of particle size influence on dispersion in the duct. ► Prediction of realistic velocities for both the fluid and the particle phases. ► Good agreement with data for a range of test cases.
