利用Gambit、Fluent等软件对电液伺服阀中的自由流和附壁流两种流态之间的切换现象进行了可视化研究，仿真出流态切换产生时滑阀副处的流场分布，并通过适当的措施，消除了流态切换现象。
利用Gambit、Fluent等軟件對電液伺服閥中的自由流和附壁流兩種流態之間的切換現象進行瞭可視化研究，倣真齣流態切換產生時滑閥副處的流場分佈，併通過適噹的措施，消除瞭流態切換現象。

The visualization research was done on flow switching phenomenon between the free jet and the reattached flows for the spool of the electro hydraulic servo valve by using Gambit and Fluent software.The flow field distribution when the flow switching phe-nomenon occurred in slide valve pair was simulated.The appropriate measures to eradicate the flow switching phenomena are adopted.
