Problems solved by technology

What is even more unfavorable is that when the foam enters the test section, it will have a great impact on the measurement results of various parameters (flow rate, pressure difference, etc.), which in turn will greatly deviate the overall results

Description

technical field [0001] The invention relates to the research field of drag reduction characteristics of surfactant solutions, in particular to an experimental device for drag reduction characteristics of surfactant solutions. Background technique [0002] Adding a small amount of surfactant to the fluid can greatly reduce the frictional resistance of the fluid in the turbulent state, and can achieve the purpose of energy saving. Therefore, surfactants have been successfully applied to the fields of ship transportation, oil exploration and transportation, and water delivery systems. However, under the background of energy shortage in the world and strong promotion of energy conservation and emission reduction, the application fields of surfactants need to be continuously expanded. It is particularly important to conduct experimental research on the drag reduction characteristics of different surfactant solutions, and to find the best performance drag reduction active agent f...
