Abstract

An experimental study is presented to determine the influence of liquid pool temperature on splashing behavior. Water droplets with initial diameter of 3.1 mm 0.1 mm impacted a water pool 40 mm in depth. The impaction process was recorded using a high-speed digital camera at 1000 frames/s. The impinging droplet was fixed at room temperature and the liquid surface was heated using a hotplate. To determine the critical We number for splashing, the impact velocity was varied. The critical impact Weber number for splashing was found to be dependent on liquid pool temperature, decreasing with an increase in surface temperature.
