Abstract

The invention relates to the technical field of droplet generation devices, in particular to a double-droplet generation device capable of being controlled separately. The double-droplet generating device capable of being controlled respectively comprises two sets of single-droplet generators, two sets of single-droplet generators and two sets of single-droplet generators, wherein each single-droplet generator is provided with a nozzle capable of spraying downwards; one set of single droplet generator is mounted on the displacement platform and can horizontally and linearly slide along the displacement platform, and the two nozzles are driven to be close to or far away from each other in the sliding direction; and the scale is mounted on the single droplet generator and is suitable for measuring the distance between the two nozzles. According to the double-liquid-drop generating device capable of being controlled separately, the two single-liquid-drop generators can be controlled separately, and the distance between the two liquid drops, the diameter of the liquid drops, the generating time and the speed can be adjusted, so that the double-liquid-drop generating device can be suitable for experimental research.

Description

technical field [0001] The invention relates to the technical field of droplet generating devices, in particular to a separately controllable double droplet generating device. Background technique [0002] Droplet impact on solid or liquid surfaces is ubiquitous in nature, aerospace and industry and agriculture, and the study of droplet collision can provide guidance for its application. In nature and industrial production, when a droplet collides with a solid or liquid surface, multiple droplets collide at the same time or successively. However, the current experimental research on droplet collision is mostly a single droplet, and the influence between droplets cannot be studied. This is mainly due to Droplet generators are limited to single droplets. [0003] There are two main types of existing double-droplet research: one is based on numerical simulation and lacks experimental support; the other is a multi-droplet generator applied in industrial production, but this gen...
