Abstract: High-speed photography and pixel analysis methods are used to study the droplets impact on the inclined dried wall. The effects of different inclined angles and Weber number (We) on droplet splashing and spreading are analyzed. It is concluded that the increasing of the inclined angle is beneficial to suppress the droplet splashing; when the We is constant, the front spreading factor of the droplet increases with the increasing of the inclined angle, while the back spreading factor decreases with the increasing of the inclined angle; the front and back initial spreading velocity of the droplet is larger than the impact velocity of the droplet, and decreases with the increasing of the inclined angle.
