Self-Induced Pulsating Liquid Flow in a Hydraulic System

摘要

Pulsating liquid flow of large amplitude in a system containing a tank, a tube and a valve which has an elastically supported plate is investigated. The functions of the flow properties versus some nondimensional parameters were found. These parameters depend on supply pressure, inertia of the liquid and of the valve as well as on the elasticity of the plate support and the dimensions of the system. The occurrence of cavitation zones in the liquid flow is taken into account. Theoretical and experimental results are compared. Both show that the amplitude of the pressure can exceed supplied pressure.
