Abstract

Abstract: 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 three main components: the liquid-solid two-phase flow model,
erosion model and corrosion model. The Euierian-Lagranglan approach is used to simulate
liquid-solid two-phase flow, while the stochastic trajectory model was adopted to obtain
properties of particle phase. Two-way coupling effect between the fluid and the particle
phase is considered in the model. The accuracy of the models is tested by the data in the
reference. The comparison shows that the model is basically correct and feasible.

Key words: ercsion-corrosion, liquid-solid two-phnse flow, stochastic trajectory model, two-way coupling
