Arno is assistant professor of Dredging Engineering at Delft University of Technology, in the Netherlands and lectures in hydraulic transport and rheology of slurries. He is also a senior researcher/adviser at the Ecology and Sediment Dynamics Department of Deltares with 35 years of experience. Key qualifications relate to dredging, sediment dynamics, rheology, slurries in mechanised tunnelling, slurries in mining and hydraulic transport. Experimental research into these subjects has led to many new findings.

The effect of density waves and slurry dynamics on slurry pipeline flow assurance cannot be predicted with current slurry pipeline design methods. Current methods are based on steady-state assumptions, assuming that the mixture velocity and density are constant in time and in the pipeline. Therefore, using current design methods a dynamically stable pipeline cannot be guaranteed. Furthermore, new experiments in vertical pipelines show that density wave amplification is possible at mixture velocities far above the critical velocity. This article presents a new temporal design method based on 1D Driftflux CFD, which is able to model growing density waves.
