Webb15 jan. 2024 · However, these studies only focused on the types of surface microstructures rather than the influence of the dimensions of the V-shaped groove. The erosion resistance is closely related to multiple parameters of the surface microstructure, such as the opening degree, width, spacing, and depth. WebbThe prevailing view is that a water droplet on a wedge-shaped groove always moves towards the wider end. In this paper, however, molecular dynamics simulations show that a water droplet can move towards the narrower end if placed at specific positions. shang dynasty definition world history
