摘要
本文利用流场可视化技术对液压滑阀中的流场进行了实验测量。通过对相似模型中的速度场进行图象采集，经过图象处理与分析，得到了流场内某些点上速度的近似值，并通过插值方法得到全流场的速度。
The present paper studied the fluid flow in a spool valve chamber using Particle image Velocimetry technology.the focused field in an experimental model,whose dimensions are decided according to similarity principles,is displayed by many tracing particles,and recorded in a computer as digital images.Using digital process technology, we calculated velocity vectors on points where tracing particles located,and made out the whole flow field by interpolating method.
