Abstract
We study in this paper the influence of the aspect ratio of an axisymm etric drop on the spreading rate. For very small values of aspect rati o, the spreading rate is proportional to the cube of the aspect ratio as stated by Tanner's law. However, as the value of the aspect ratio i ncreases, the proportionality constant shows a weak dependence on the aspect ratio, first decreasing and then increasing after reaching a mi nimum. Due to the fact that the aspect ratio of the drop decreases wit h time in the spreading drop, its influence decreases as time increase s. [S1063-651X(98)09109-0].
