Abstract

The invention discloses an experimental device for researching the law of change in the motion and collision process of droplets. The experimental device comprises a single droplet generation system, a droplet radiation field motion research system, a droplet collision law research system, and a parameter measurement and record system. The droplet collision law research system includes a material wall heating module, a collision speed adjustment module, and a collision angle adjustment module. The experimental device of the invention can be used to measure the size change and velocity change of droplets, research the law of motion of droplets in a simulated fire field (radiation field), microscopically research the law of spreading, splash and spring-back of droplets when droplets collide with a material at different incident angles and incident speeds, and microscopically research the law of spreading, splash and spring-back of droplets when droplets collide with materials with different surface temperatures.

Description

technical field [0001] The invention relates to an experimental device for studying the change law of droplet motion and collision process with a wall, mainly involving the motion and collision process of droplets in various parameters such as external radiation, wall temperature, collision speed, and collision angle. Background technique [0002] Water sprinkler fire extinguishing technology has been widely used in fire safety system because of its non-pollution and high fire extinguishing efficiency. However, for some specific occasions, such as fires on high-rise building facades and space shuttle fires, due to the limitation of water flow and pump pressure, it is difficult to extinguish fires, that is, how to achieve the minimum amount of water to extinguish fires is particularly important. Droplets evaporate in the radiation field produced by fire and collide with the wall of the burning material, resulting in mass loss. It is necessary to optimize the water spray syste...
