Abstract

Experimental observations concerning various outcomes during a single liquid drop impact on inclined wetted surfaces are performed using a high-speed digital camera. A 30 vol% glycerol/water solution, butanol and heptane are adopted as the fluids. At an impact angle ranging in 28.0°–74.7°, outcomes after impact including spreading, the jet sheet and splashing definitely emerge in succession with the Weber number increasing, whereas both rebound and partial rebound are random through numerous repeatable tests and they can only be observed at smaller impact angle, lower Weber number and higher viscosity. The increment in the Ohnesorge number results in smaller spreading factors, and its effect becomes weak at the small impact angle. The decrement in the impact angle leads to a rising front spreading factor, while the back one shows the opposite trend. In addition, the front spreading factor also can be increased by increasing the Weber number, but the back one varies less. Finally, several three-dimensional simulations are undertaken. Results reveal that the spreading factor in the normal direction can be decreased by reducing the impact angle, whereas the Weber number influences are minor. Also the decrement in the impact angle will enhance the pressure accumulation in the front direction inside the pre-existing film. This research provides some basic particularities for a drop impact on inclined surfaces.
