Resumo
The erosion causes several damages to the hydraulic surfaces whether by cavitation or by abrasion, and can compromise structures safety. In the first one, the water high speed reduces its vapour pressure and bubbles implosion quickly damages the material whereas in the second one, water-solid mix slowly removes surfaces material. It is clear that different materials show various behaviors when exposed to erosion by abrasion and a number of apparatuses were depeloped to evaluate the resistance to erosion by abrasion. In this research, the aim was to develop through computational fluid dynamic a mathematical method to evaluate the concrete resistance to erosion by abrasion, based on existing aparattus.
