Abstract

The invention discloses a liquid drop collision generation device. The liquid drop collision generation device is mainly divided into a liquid drop generation module, a shooting module and a single chip; a flow type peristaltic pump is a liquid supply device of a first liquid drop generator and a second liquid drop generator and can control the grain size of the generated liquid drop; a gas pump is a gas supply device of the first liquid drop generator and the second liquid drop generator and can give the initial speed of the liquid drop; the single chip is connected with a first stepped motorand a second stepped motor and can control the collision angle of the first liquid drop generator and the second liquid drop generator; a high-speed video camera is fixed on an objective table; the objective table is connected with a first sliding guide rail and a second sliding guide rail through a first linear bearing and a second linear bearing; and the single chip is connected with a third stepped motor and controls the up-and-down motion of the video camera to shoot the collision process of the liquid drops. The liquid drop collision generation device can accurately control the grain size and the speed of the liquid drops, can control the collision angle of the liquid drops in real time, and is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of droplet generation and collision, in particular to a droplet collision generation device with controllable velocity, particle size and collision angle. Background technique [0002] The phenomenon of droplet collision is ubiquitous in nature and industry, and has a wider range of applications in chemical engineering such as spray combustion, biopharmaceuticals, aerospace, and dairy processing. It is of great theoretical and practical significance to carry out in-depth research on droplet collision. The droplet type, droplet diameter, droplet collision velocity and angle have an important impact on the droplet collision results. [0003] The droplet generating device is mainly used for observation experiments on the deformation, collision, and breaking of droplets. At present, most of the existing droplet generating devices have complex structures and high implementation costs, and cannot achieve precise ...
