Abstract
The article presents theoretical and experimental researching of hydrodynamic processes in hydraulic drives of vehicles, road building and mining machines. In this work, analyze the influence of hydrodynamic processes on the development of the turbulent flow of a fluid through a “pipeline-fittings” system. The analysis based on the numerical solutions of the Navier–Stokes equations for the velocity field. The research examines the dynamics of fluid flow in the hydraulic system “pipeline-fittings” with the main parameters: flow rate in a system from 20 l/min to 60 l/min, diameter of the pipeline 1/2″ and fittings DKOL standard. The methodology for modeling fluid flow in theoretical studies included high pulsations of the fluid and turbulence calculated. In the experimental part, the losses in the hydraulic system studied with one, two and three fitting connections.
