✦ Synopsis
A video motion analysis system was used with two di †erent monodisperse droplet generators to quantify droplet impaction and any consequent reÑection. By using di †erent magniÐcation/droplet generator combinations, droplet impaction was detailed at various stages. Low (7]) magniÐcation, together with a generator that produced a spray cloud, allowed determination of the height and numbers of droplets reÑected from plant surfaces. Higher (15]) magniÐcation and a single-drop generator enabled the trajectory, and changes in velocity, of a rebounding droplet to be followed. By using high (90]) magniÐcation and the single-drop generator, detailed measurements of a droplet deforming on impact could be made. Examples of how these techniques could be used are given.
