Simulation and analysis of the impact of micron-scale particles onto a rough surface

Simulation of Erosion by Particle Impact on a Rough Surface

“…The results are compared with those of the previous studies on smooth surfaces. In the whole study, criterion of erosion rate calculation is the sum of all the elements with strain of more than %0.2 [17].…”

“…In order to justify this difference, the difference between shapes of rough and smooth surfaces should be expressed. Yildrim et al [17] studied the difference of mechanical impact between smooth and rough surfaces. According to their work, when the particle diameter was comparable with the surface roughness, mechanical impact onto the rough surface was different from the one on the smooth surface [17].…”

“…Their diagrams showed that rebound velocity on rough surfaces was higher than that on smooth surfaces and, as particle diameter became larger, the difference between rough and smooth surfaces became lower because of omitting surface roughness with large particle diameter [17].…”

“…Particle parameters include size [13][14][15][16][17], velocity [15,17], impact angle [2,6], density [14], shape [3], mechanical property [15], and impact location [17]. It is obvious that particles have an amount of energy before they impact on the target surface.…”

“…Yildirim et al [17] compared the effect of particle size and velocity between smooth and rough surfaces. Their study showed that surface shape is an important parameter that affects energy absorption, target erosion behavior, and particle rebound response.…”
