A numerical investigation of solid particle erosion experienced within oilfield control valves

TL;DR: In this article, a computational fluid dynamics erosion model is presented, which allows erosion rates within chokes to be predicted using particle trajectories computed through the momentum exchange from turbulent flow field, while erosion rates are predicted as a function of individual particle impact characteristics, given material types, particle shape and size.
