CFD Simulation of Sediment Dispersion using STAR-CCM+

December 18, 2019

The sediment is injected at the far end of the pipe, down stream of the main inlet, and is modeled as a Lagrangian Multiphase. Here, the motion of the sediment particles is calculated through the main continuum phase of the fluid in the pipe. The particles varied in size as defined by a distribution provided by the end-client. The fluid makes two 90° bends through a pipe coupling and a sharp bend through a tee, which causes a significant amount of swirl in the fluid.


Our analysis showed much of the injected sediment was getting caught up in this swirl and pushed to the outside of the pipe walls. The results were able to clarify measurement observations the end-client had from test.
