Erosion and Abrasive Machining

Erosion from solid particles — whether abrasive slurries moving through pipelines, sediment-laden water striking hydro turbine blades, or high-pressure waterjets used in precision cutting — gradually removes material from surfaces in ways that are difficult to predict and costly to ignore. Researchers combine controlled laboratory experiments with computational fluid dynamics simulations to understand how particle size, velocity, angle of impact, and fluid chemistry interact to determine how quickly a given material wears down or corrodes. A central challenge is that erosion and corrosion rarely act in isolation; in marine environments or oil and gas wells, the two processes accelerate each other in ways that simple additive models fail to capture. Active work focuses on developing materials and surface treatments with higher wear resistance, and on building more accurate simulation frameworks that can guide the design of components — from pump impellers to pipeline elbows — before they reach the field.
