The invention discloses a
visualization experiment device and method of wall collision of high-temperature
molten metal droplets in a negative pressure environment. The experiment comprises: an air flotation damping experiment table, a
metal droplet generation
system, a temperature controllable wall surface
system, an environment pressure adjustment
system, an automatic trigger high-speed camera system and an
image analysis system. The
metal droplet generation system generates
metal droplets; the environment pressure adjustment system realizes the precise control of the environment pressure within a greater negative
pressure range when the droplets collide the wall surface; and the automatic trigger high-speed camera system records an image when the droplets collide the wall surface, and finally, the
image analysis system performs quantitative analysis on a video to provide accurate physical variables such as a droplet speed, a droplet
diameter, a spreading
radius, a height and deformation characteristics. By adoption of the experiment method, the
metal droplets can be generated in the negative pressure environment, and an experiment scheme is provided for the mechanism research ofthe movement characteristics when the
metal droplets collide the wall surface. The method is simple in operation, safe and reliable in process, and wide in experiment research application value.
