Liquid droplets impinging onto a slender circular cylinder were experimentally studied using a high-speed camera. Water, acetone and olive oil droplets were tested. Weber numbers for each liquids were in the range of 5.9-100, 14.6-248 and 11.6-197. The target brass cylinder diameter was 2.38 mm. Front and side view of droplet dynamic behaviors were depicted and analyzed with respect to Weber number. Maximum spread length and re-collision phenomena were analyzed.
