Original publication title: Research on the Anti-Erosion Mechanism of the Shell Surface Structure Based on Numerical Simulation.
Plain-English summary
This study looks at how certain shell surfaces can resist wear and tear when exposed to flowing liquids and solid particles. Researchers used computer simulations to compare smooth shells with ribbed shells, finding that ribbed shells experienced 29.08% less erosion when the flow hit them at a right angle. The particles also hit the ribbed shells with less force, which was 15.91% lower than on smooth shells. This happens because the grooves in the ribbed shells create a slower flow of liquid, giving the particles time to slow down before they hit. The findings suggest that ribbed designs could help improve equipment that often gets damaged by erosion.
Abstract
This paper introduces a biological surface that is resistant to erosion under liquid-solid two-phase flow. Numerical simulations are used to study the erosion of smooth and ribbed shells by particles. The results show that when the flow direction is perpendicular to the direction of the shell ribs, the total erosion rate of the ribbed shell is 29.08% lower than that of the smooth shell, and the impact velocity of particles with a diameter of 0.5 mm on the ribbed shell is 15.91% lower than that on the smooth shell. This phenomenon occurs because a low-velocity flow field is formed in the grooves of the ribbed shell, which causes the particles to decelerate for some time before impacting the shell. This ribbed structure may provide design ideas for equipment that is susceptible to erosion.
