Studies of turbulent flow characteristics of dividing open water streams

Abstract

The movement of water in the areas of division of open streams has a particularly turbulent character. For a detailed study of river bed processes, it becomes necessary to identify the patterns of turbulent motion [1]–[29].The aim of these studies was to study and determine the turbulent characteristics of the flow and to establish the relationship between the intensity of flow turbulence with the channel deformations observed.Theoretical and experimental research methods, laboratory studies, field surveys of existing water intake units were used. When processing the results of experimental studies, the methods of mathematical statistics were used.On a specially constructed hydraulic model, detailed experimental studies of the flow structure in the fission unit were carried out under conditions of rigid and eroded channels. [3], [28], [29].Detailed studies have revealed the kinematic structure of the flow in the section of flow division.The nature of the change in the intensity of the turbulent characteristics of the flow in different sections of the fission unit in rigid and eroded channels is determined.The relationship between the nature of the change in the flow turbulence intensity and the channel deformations observed in the division unit has been established.
