Introduction of Representative Flow Oscillations and Experimental  Visualization Methods in Hydraulic Valves
LU Liang, HE Cheng-peng
Serious oscillating flow frequently occurs in hydraulic valve ports, which causes complex gasliquidsolid coupling excitation problems, such as cavitation, selfexcited oscillation and structural vibration. With the use of flow visualization experiment method, these phenomenons can be caught visually, which helps understand the physical nature of the phenomenon, reveal the internal mechanism of the problem, obtain the basis of modeling and put forward effective solutions. Based on the analysis of the experimental research progress for flow visualization in hydraulic valve port, this paper introduces the visual experimental methods of “watching”, “listening” and “acting” from a generalized view.
