Abstract
The aim of this study is to develop a combined mathematical and computational fluid dynamics based model for the prediction of erosion–corrosion rates in fluid transport pipelines which is one of the critical problems that every productive industry may encountered with. The effects of reattaching and detaching of flow lines, which are common in pipelines, are considered in this study. In order to validate the developed model, the predicted results are compared with experimental data in a practical geometry. Two-phase saline water containing 2 % by volume silica at 30 °C is considered as the studied fluid. High Reynolds number within the system ensured using a turbulence model for predicting the fluid pattern of the system. For obtaining the overall erosion–corrosion model parameters, simulation was done by using a finite element code. The predicted wear profile matched closely with the experimental data and the presented model provided high accuracy predictions for pipelines with straight and contracted geometries.
