  • The solid-liquid phases(sand and water) flow field,inside a hetero-diameter pipeline,was empirically approximated,mathematically formulated by Standard k-ε Turbulence/Cavitation/Erosion models,theoretically analyzed,numerically simulated with Fluent and experimentally evaluated with the lab-built test platform.The influence of the temperature and intake flow velocity on the distributions of erosion/cavitation on pipeline walls was investigated.The simulated results show that the flow velocity has a major and temperature has a minor impact.To be specific,as the flow velocity increases from 2 to 5 m/s,the erosion rate increases,accompanied by weak temperature dependence,and the cavitation starts appearing at 5 m/s only at the input.When it comes to the simulated and measured “unstable erosion lengths”,the discrepancy was below 2%.We suggest that the simulated results be of some technological interest in industrial design and applications of solid-liquid slurry flow pipelines.
