Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] see figure 1 , the present invention includes a head tank 4 for containing fluid I, the bottom of the head tank 4 communicates with a transparent round tube, a flow meter 7 and a first valve 8 are arranged on the round tube; several needles 6 are arranged at the entrance of the round tube, The needles 6 all have a second valve, and the second valve is a pulse valve. The needles 6 are all connected to the ink bottle 1, the ink bottle 1 is installed on the ink bottle support 2, and the ink bottle support 2 is arranged above the high position tank 4. The fluid II is housed in the ink bottle, and the colors of the fluid II and the fluid I are different and can be miscible; the fluid I generally adopts a colorless liquid such as water, and the fluid II can adopt a colored dye such as red ink.

[0037] The bottom of the elevated tank 4 is provided with a w...

Abstract

The invention relates to a fluid velocity distribution experiment instrument and a using method thereof. The fluid velocity distribution experiment instrument comprises a high-level tank used for containing fluid. A transparent round tube is communicated with the bottom of the high-level tank, and a first valve is arranged on the round tube. A plurality of needles are arranged at the position of an inlet of the round tube and are connected with an ink bottle, and each needle is provided with a second valve. According to the fluid velocity distribution experiment instrument, the high-level tank is arranged to contain the fluid which is discharged through the transparent round tube, the needles are arranged at the position of the inlet of the round tube, colored fluid is introduced to the flowing fluid in the round tube through the needles, fluid velocity is controlled by adjusting the first valve, the colored fluid is controlled to flow out of different needles through the second valves, so that laminar and turbulent flow demonstration is conducted, the flowing velocity distribution state of the fluid in the round tube can be simulated, and visual observation can be achieved. The fluid velocity distribution experiment instrument can help students understand the velocity distribution state of the fluid in the tube and the concepts of a boundary layer and a laminar sublayer during teaching demonstration.

Description

[0001] 【Technical field】 [0002] The invention belongs to chemical engineering principle experimental instruments, in particular to a fluid velocity distribution experimental instrument and a using method thereof. [0003] 【Background technique】 [0004] When the fluid flows in a circular tube, the fluid velocity distribution is uneven on the cross-section of the circular tube. The fluid velocity on the axis of the pipeline is the largest, the closer to the tube wall the smaller the fluid velocity, and the fluid velocity in contact with the tube wall is zero. . At present, there is no experimental instrument to reflect the velocity distribution of fluid flowing in a circular tube, which makes it difficult for students to understand the velocity distribution of fluid and the concept of boundary layer and laminar inner layer. [0005] 【Content of invention】 [0006] The object of the present invention is to overcome the problems existing in the prior art, and provide a fluid v...
