Title of the articleMODELLING QUASI-STATIONARY PROCESSES OF FLUID FLOW
Abstract.A number of hydraulic networks operate with a change in consumption over time. On the developed experimental setup experiments with the definition of hydraulic resistance coefficient of friction in quasi-stationary regimes of fluid flow through pipelines of various diameters (from DN 15 to DN 32 mm) were taken. The frequency change rate of 1 to 5 Hz. Mode of operation of the network device was set the pulse frequency of its own design. The device is the problem of impulse frequency is a valve of a special section moving in a horizontal direction. Moving the valve unit pulse frequency was carried out by means of an electric motor. Reading data obtained in the experimental setup were fed to a PC and cultivated. The experiments were obtained depending on the coefficient of hydraulic resistance of friction for the quasi-fluid flow regime for the standard steel pipes.
Keywords.Hydraulic regimes, a quasi-stationary operation, pulsation, variable flow.
