Caption
Erosive wear occurs in many processes involving particles which hit a wall with large relative velocities. Even though the material removal for each impact is very small the collective damage is often significant. The video displays the wear in bent pipes which is caused by particle impacts due to gravity. On the left, dry particles enter the pipe. In the center, the particles are surrounded by a fluid with low viscosity and on the right by a fluid with high viscosity. The color coding of the semi-transparent pipes reflects the amount of wear ranging from low (blue) to high (red). The the overall wear decreases with increasing fluid viscosity. The simulation was carried out using SimPARTIX.
