摘要：The impact of droplets on the surface is a common phenomenon. The outcome of a droplet impacting on a solid surface depends on the properties of the liquid, the surface conditions and the kinematics parameters, i.e. velocity and momentum. During the impact process, the phenomenons, such as spread, rebound, often appear. This paper presents the results of an experimental investigation of droplets impacting on inclined solid surface at low velocity. The effects of the impact parameters on the droplet impingement are studied. Measures were performed using a high-speed camera. It has been shown that the impacting droplets spread on the surface until liquid surface tension and viscosity overcame inertial forces, after which they recoiled off the surface. The maximum diameter of a droplet spread was measured. In addition, a further forecasting expression has been obtained through energy model when a droplet impacts on an inclined surface without splashing. It is found that it is in good agreement with experimental value and can well predict the maximum spread diameter. (C) 2009 Curtin University of Technology and John Wiley & Sons, Ltd.
