摘要

Erosion-corrosion of liquid-solid two-phase flow occurring in a pipe with sudden expansion in cross- section is numerically simulated in this paper. The global model for erosion-corrosion process includes includes three main components: the liquid-solid tow-phase flow model, erosion model and corrosion model. The Eulerian-Lagrangian approach is used to simulate liquid-solid two-phase flow, while the stochastic trajectory model was adopted to obtain properties of particle phase.
