Test device for researching motion characteristics of jet flow in linear stratification water body

The utility model relates to a test device for researching motion characteristics of jet flow in a linear stratification water body, which comprises a test water tank, overflow discs for generating the linear stratification water body are arranged at four corners of the bottom of the test water tank, water inlet pipes are arranged on the overflow discs, and the water inlet pipes are communicated with the interiors of the overflow discs; each first water outlet pipe is internally and sequentially provided with a first flow speed controller used for controlling the water flow speed and a first water body heater used for heating a water body in the water flow direction; each second water outlet pipe is internally and sequentially provided with a second flow speed controller for controlling the water flow speed and a second water body heater for heating the water body in the water flow direction; and the high-speed camera is used for recording the jet flow movement process and is arrangedon one side of the test w
