title = "Temperature-dependent viscosity effect on drop impact dynamics",
abstract = "Drop impact on a heated substrate is one of the most important objects occurring in the main two types of cooling applications such as quenching of metals and the cooling of lasers and electronic devices. The paper reports a study of the interaction of the water drop of 10?μl impacting on a heated sapphire plate with a temperature varied within a range of 23-80°C. Dynamic viscosity at this temperature range is decreased from 1004 to 355.1×10-6?Pa·s. The influence of the temperature on liquid viscosity may lead to a substantial difference in drop dynamics. The main changing parameters are the liquid column at splashing and secondary droplets atomization. A considerable decrease of the liquid column contact diameter and an increase of the liquid column height at the splashing stage are shown with the decreasing viscosity. Secondary droplets atomization from the liquid column with increasing temperature is revealed. ",
