dc.description.abstract |
Droplet impacts on a solid surface are natural and essential phenomenon in many industrial applications such as ink-jet printing, spray cooling, combustion engines, laser-induced forward transfer and thermally sprayed coatings. Numerous studies have focused on understanding the impact, spreading and splashing of droplets with different diameter- and velocity-scales, with or without considering the solidification behaviour. In the formation of plasmasprayed splats, different droplet spreading behaviour such as fragmentation, finger splashing and disk shapes have been observed. Several research groups [1–5] have developed experimental techniques consisting of high-speed cameras and pyrometers to follow droplet spreading and understand the splat formation mechanisms. On substrates with the presence of surface adsorbates/- moisture, droplets tend to overspread leading to the holeinduced fragmentation, with a small fraction of material remaining on the substrates [6–8]. On substrates preheated above the socalled transition temperature where the surface adsorbates/moisture vaporises, the phenomenon of splat fragmentation disappears and splats with regular shapes begin to form [9–11]. Nevertheless, droplet finger splashing is frequently observed even above the transition temperature. |
