控制道下移双稳元件中的射流附壁点位置的研究

Investigation on the Location of Jet Wall-attachment Point in Bistable Fluidic Elements with Down Shifted Control Channel

本文阐述了射流附壁点的位置与附壁式射流元件的位差及张角等参数的关系,从而为进一步设计有别于国外的控制道下移的附壁式双稳元件打下基础。全文共分四部分:一、问题的提出:二、射流附壁点的解析表达式及理论分析;三、射流附壁点的实验研究与分析;四、结论。

This paper investigates the relations amony the position of fluidic wallattachment point, setback, wall angle and other parameters of a wall-attachment bistable fluidic element. It serves as a guide for the further desigrt of wall-attachment bistable fluidic elements with down shifted control channel, which is different from ordinary design in other countries. The paper includes: (1) Raise of the problem, (2) Analytical expression and theoretical analysis of fluidic wall-attachment point, (3) Experimental investigation and analysis of fluidic wall-attachment point, and (4) Conclusions.
