Abstract: The impact of a liquid drop in the region between rivulets on the surface of a locally heated falling liquid film and the effect of this disturbance on the development of wave processes in the film have been studied. It is established that perturbations caused by the incident drop are spreading downstream and not going beyond the region bounded by the adjacent side rivulets. The maximum increase in the amplitude of waves in the film is observed in the same region between rivulets. At a distance of 70 mm downstream from the site of impact, the amplitude of waves in this region exhibits a 40–60% increase in comparison to the undisturbed film.
