An experimental investigation on the characteristics of the liquid sheet formed by the impingement of two capillary liquid jets was conducted. The focus of the study was on the liquid instabilities that occurred at the edges of the sheet.This work first identified three breakup regimes of the liquid sheet, and then focused on the capillary breakup regime, where a stable closed-rim sheet existed. The distribution of fluid velocity on the sheet was examined. In addition, the dimensional characteristics of the sheet were studied and new equations were derived for the thickness and shape of the sheet.The breakup of the droplets from the edges of the sheet was investigated by using direct visualization. The process of generating droplets was divided into two stages: growing stage and detaching stage. Detailed analysis was provided. Theoretical and experimental studies were completed to find the distribution of the sheet edge velocity.
