This paper presents an experimental investigation on the extent of water splash resulting from the collision of a flat water jet onto a vertical surface. The water sheet spread on the plate and its splash, as a result of water breakup, are the most significant phenomena that affect water delivery to marine and offshore structures. In an arctic environment, wave impact and splash can significantly affect ice accretion on a marine structure. To predict ice accretion, water sheet breakup behavior onto a surface needs to be studied closely. The motivation of this experimental study is to further examine water sheet splash. The tests performed in the lab scale setup comprise of high-speed image capture from a water jet-vertical surface collision at various attack angles, which cause mild to severe breakup situations. The results show that variation in jet velocity significantly affects the height, width and splash area of a water sheet. The results also show that attack angle is another significant factor for water trajectory and therefore water shedding beyond the vertical surface. The interdependence in between water trajectory and water shedding provides a new correlation of water transport after water sheet breakup.
