Abstract:	This experiment investigates the impact outcomes of ethanol drop on a moving inclined surface at the various inclined angles and moving velocities. The gravity not only can promote the instability of the expanding film at downward flow but also can stabilize the film at upward flow during the drop impact onto a stationary inclined surface. Considering the horizontal moving surface, the surface velocity excites the occurrence of splashing that is toward the opposite direction of surface movement, whereas it suppresses the splashing in the same direction of surface movement. When the inclined surface moves downward at a proper surface velocity, the impact outcomes can be changed from downward splashing to deposition, and furthermore, the direction of splashing also can be changed to upward by increasing the surface velocity. The regime of deposition will be enlarged by an appropriate surface velocity, and this tendency is more obvious with a larger inclined angle. (C) 2010 Published by Elsevier Ltd.
