     Analysis of Control Valve Instability Induced by Unsteady Sophisticated fluid flow
     Tu Shan et al
     By making three-dimensional visible experiments of several typical control valves using PIV technology and corresponding numerical simulation，the unsteady flow characteristic and mechanism are grasped The valve stability and thermal efficiency is improved by eliminating and decreasing the unsteady flow so as to modifying valve profiles.
     Keywords：control valve，sophisticated fluid flow，stability，oscillation，flow vision，measurement
     1　前言
     调节阀是流体机械(包括电力机械、化工机械、流体动力机械等)中控制通流能力的关键部件，它的工作性能、安全性与整个装置的工作性能、效率、可靠性密切相关。影响其工作性能的因素很多
