AB - This research work represents an experimental study of the interaction  between water drops deposited on a substrate at ambient temperature. To  examine this phenomenon, the evaporation of a single drop deposited on a  substrate was first investigated. Then, several drops were deposited  alongside on the same substrate under the same conditions. The central drop  dynamic behavior was also examined and compared with that of a single drop.  This comparison shows the effect of the interaction between the neighboring  drops, which delayed the evaporation of these drops and particularly the  central droplet, on evaporation. In fact, three configurations were studied  by changing the initial distance (d) between the drops (d = 0.2 mm, d = 7 mm  and d = 15 mm). The obtained results reveal that the interaction phenomenon  becomes less important by increasing the distance between the drops. This is  important for optimizing many industrial applications, such as spray drying,  fuel injection in combustion engines, and other applications.
