Spreading behavior of droplets impacting over substrates with varying surface topographies
TL;DR: In this article, the effects of velocity and surface temperature on spreading dynamics were investigated by impacting single droplets for Weber numbers between 67 and 565, and the results showed that the maximum spreading factor at both spray-coated and combined surfaces is larger than the model predictions.
