摘要：

Packets of capillary waves on the surface of a horizontal water layer generated at coalescence with a layer of microdroplets (with a characteristic diameter of 50-100 mu m) of the dissipative structure "droplet cluster" have been detected by high-speed video recording and the schlieren method. The shortest experimentally observed waves have a length of about 130 mu m and their phase velocity exceeds 1.8 m/s. It has been found that the coalescence of a single drop initiates a self-sustained wave process, which induces the coalescence of hundreds of droplets in a time shorter than 1 ms, which form a cluster.
