Abstract
In this study we investigated the phenomena of liquid-droplet impact the solid surface and displayed a certain appearance of the semicircle liquid film on the solid surface after impacting.In the aspect of single droplet impacting, we used distilled water and primary parameters were impact velocity, roughness and material of solid surface. Compare the result with previous reseachers’.
We also used a hemispherical water film was formed after impacting solid surface, then fixed first water droplet may regard as a hemispherical film. Primary parameters were size and velocity of droplet and used different species liquid included hexadecane, decane, water and
lsopropylalcohol. Then discuss the phenomena during impact process.
