Abstract

The invention relates to a micro-bubble pipeline drag reduction method. Micro-bubbles are directly generated in a transition layer of a turbulent flow field in a pipeline through electrolysis by an electrolytic ring, the micro-bubbles interact with turbulent flows in the transition layer of the flow field, turbulent flow fluctuation is inhibited, and flowing turbulent flow drag reduction is realized. A micro-bubble drag-reduced pipeline comprises a pipeline body, wherein the section of the pipeline body adopts a rectangular structure, a two-dimensional groove channel is formed in the pipeline of the pipeline body, two ends of the two-dimensional groove channel are connected with the rectangular pipeline body respectively in a sealed manner, the electrolytic ring is arranged in the two-dimensional groove channel and adopts a rectangular frame structure, the electrolytic ring is fixedly arranged in a transition layer area in the two-dimensional groove channel, and a lead of the electrolytic ring extends out of the two-dimensional groove channel to be connected with a power supply. By the aid of interaction of the micro-bubbles and the turbulent flows in the transition layer, the turbulent flow fluctuation is inhibited, the flowing turbulent flow drag reduction is realized, the frictional drag in a liquid pipeline delivery process is reduced, the drag reduction efficiency is improved, unnecessary waste is reduced, and the delivery speed of a fluid is increased as far as possible under the same micro-bubble air quantity.

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 ...
