摘要： Droplet impingement experiments for a wide range of Weber numbers were conducted by digitizing silhouettes of impacting water drops onto a tailored grinded graphite substrate, typified by randomly distributed cavities on a generally smooth surface. The aim was to investigate if the anchoring of the triple line, due to friction forces generated by dilute superficial defects, could be observed for drop impingement experiments. During the early inertially dominated spreading phase, the drops showed similar behaviors independently of the initial impact velocities. However, just after this phase, droplets impacting at low Weber numbers indeed exhibited this peculiar friction-induced pinned configuration. 出版者： Amsterdam: Elsevier Inc 出版日期： 2014-02-01 出處： Experimental thermal and fluid science, 2014-02, Vol.53, p.142-146 版權： 2013 Elsevier Inc. 版權： 2015 INIST-CNRS 識別號： ISSN: 0894-1777 識別號： EISSN: 1879-2286 識別號： DOI: 10.1016/j.expthermflusci.2013.11.021
