Objective of this study is to investigate the effect secondary motion particles in multiphase gas-solid flows parametrically and test relative impacts particle shape orientation information on distribution. For that purpose, predictive accuracies simplified drag coefficient models are assessed for conditions relevant a wood recovery plant operating at dilute flow regime. After demonstrating str...

This contribution presents new phenomena regarding the stability of pressure driven flows within annular pipes. The fluid is advected downstream due to an axial pressure gradient but also subjected to centrifugal mechanisms due to the independent rotation of the coaxial cylinders that contain it. Coexistence of upstream and downstream spiral secondary flows is observed in the co-rotating regime...
