Device suitable for stably observing movement process of particles in turbulent flow field

The invention discloses a device suitable for stably observing the movement process of particles in a turbulent flow field. The device comprises a pipe flow section, a flow stabilizing groove, a water groove, a submersible pump, a high-speed dynamic shooting system and a continuous laser system. The upper end of the pipe flow section is connected with a valve and a flowmeter and communicated with the water tank, the lower end of the pipe flow section is connected with an outlet of the flow stabilizing tank, and a fixed grating is installed in the pipe flow section through nuts; the submersible pump is placed in the water tank to pump water into the steady flow tank; three partition plates are vertically arranged in the steady flow groove, small holes are formed in the lower portion of the second partition plate and are slightly higher than the other two partition plates, fluid in the steady flow groove flows through the grating from the bottom of the pipe flow section to form turbulent flow, a continuous lase
