Embodiment 1

[0032] Embodiment 1; as Figure 1 to Figure 6 As shown, a microbubble drag-reducing pipeline includes a pipe body 2, the cross section of the pipe body 2 is a rectangular structure, and the two ends of the pipe body 2 are respectively provided with an inlet port and an outlet port. Connection, the inlet end and the outlet end of the rectangular pipe body 2 are respectively provided with connecting flanges 3, which facilitates the connection of the drag reducing pipeline of the present utility model with other pipelines; There is a two-dimensional channel 10, and the two ends of the two-dimensional channel 10 are respectively sealed and connected to the rectangular pipe body 2. An electrolytic ring 101 is arranged in the two-dimensional channel 10. The electrolytic ring 101 has a rectangular frame structure. The electrolytic ring 101 Fixedly arranged in the transition layer area in the two-dimensional channel 10 , the wire 107 of the electrolysis ring 101 extends out of the two...

Embodiment 2

[0037] Embodiment 2: as Figure 7 Figure 8 As shown, a micro-bubble drag reduction pipeline includes a pipe body 2, the cross section of which is a circular structure, and the two ends of the circular pipe body 2 are respectively provided with an inlet port and an outlet port. There is an electrolysis ring 101, which is in the shape of a ring, and the electrolysis ring 101 is fixedly arranged in the transition layer area in the circular tube body 2, and the wire of the electrolysis ring 101 extends out of the circular tube body 2 to connect to the power supply.

[0038] Three baffles 106 for fixing the electrolytic ring 101 are arranged on the inner wall of the circular tube body 2. The electrolytic ring 101 is fixed in the circular tube body 2 through the baffle plate 106, and the electrolytic ring can be fixed through the baffle plate 106. 101 is more stably fixed in the pipe body 2, avoiding changing its position due to the impact of water flow.

Abstract

The invention relates to a method for reducing drag in a microbubble pipeline. In the transition layer of the turbulent flow field in the pipeline, the microbubbles are directly generated through the electrolysis of the electrolytic ring, and the microbubbles interact with the turbulent flow in the transition layer of the flow field to suppress the turbulent pulsation and realize the flow turbulence. Drag reduction. A micro-bubble drag reduction pipeline, comprising a pipe body, the cross section of which is a rectangular structure, two-dimensional grooves are arranged on the pipeline of the pipe body, and the two ends of the two-dimensional grooves are respectively sealed and connected with the rectangular pipe body. An electrolytic ring is arranged in the two-dimensional channel, and the electrolytic ring has a rectangular frame structure. The electrolytic ring is fixedly arranged in the transition layer area in the two-dimensional channel, and the wire of the electrolytic ring extends out of the two-dimensional channel to connect with the power supply. Relying on the interaction between microbubbles and turbulence in the transition layer, suppress turbulent pulsation, realize flow turbulent drag reduction, reduce frictional resistance during liquid pipeline transportation, improve drag reduction rate, and reduce unnecessary waste. In the same microbubble Increase the delivery speed of the fluid as much as possible under the gas volume.

Description

technical field [0001] The invention relates to the technical field of turbulent flow drag reduction in liquid pipelines, in particular to a flow drag reduction method for microbubble pipelines and a microbubble drag reduction pipeline. Background technique [0002] Energy shortage is one of the important issues restricting sustainable economic development and threatening human progress, so energy conservation and emission reduction have become the focus of social attention. When the fluid is transported by pipeline, the loss caused by the frictional resistance between the fluid and the wall is a major part of the energy loss, so reducing the frictional resistance in the process of fluid transport is an important form of energy saving. Although various drag reduction technologies such as surfactant drag reduction, coating drag reduction, rib drag reduction, plasma drag reduction, and wall suction drag reduction have been developed, these drag reduction methods are difficult ...
