Slurry transport is a widely used method for moving goods in various industries, including oil and gas, chemicals, and minerals. However, transporting slurries through pipeline systems poses significant risks to the integrity of the infrastructure due to erosion on the pipe walls. This can lead to equipment failure, resource loss, substantial economic impacts, and potential hazards to human safety and the environment. Despite the importance of understanding slurry erosion, studies on slurry erosion in pipelines with elbows connected in series are relatively limited, especially compared to gasbased erosion studies. Furthermore, existing research lacks detailed evaluation of the ratio of maximum erosion in the second elbow compared to the first. Additionally, the erosion models presented in the literature are often complex and difficult to apply for quick, general erosion estimation. Therefore, this project sought to address these gaps by studying slurry erosion in a pipeline with two 90-degree elbows connected in series, transporting a water-sand slurry under varying operating conditions using CFD simulations. The aim was to enhance and diversify the research in this field, complement existing parametric studies by analysing the mathematical relationships between erosion and its contributing factors, and specifically focus on the erosion ratio between the second and first elbow. Regression models were also formulated for prediction of general erosion in both elbows.
