摘要

使用16 cm×16 cm的液流收集装置

对一种典型三角形内腔的溅板式层板喷注单元两股射流的流量和撞击后混合特性进行了试验研究.通过改变三角形结构尺寸

研究了扩张角和相对厚度对流量系数和混合效率因子的影响.结果表明:随着扩张角增大

流量系数和混合效率因子先增加后减小

当扩张角在60°～75°范围中

两者都达到了最大值

分别为0.773和82.6%;相对厚度对流量系数和混合效率因子也产生了较为明显的影响.

Abstract

The flow rate and mixing characteristics of splash platelet injector element with a typical triangular lumen were experimentally investigated by using a collecting device with an area of 16cm×16cm.The effect of main configuration parameters

such as expending angle and relative thickness

on flow coefficient and mixing efficiency factor were obtained.The results show that

flow coefficient and mixing efficiency factor increase firstly and then decrease with the increase of expending angle.Both of them could reach their maximum value of 0.773 and 82.6% when expending angle is at the range of 60° to 75°.It is also found that the relative thickness has great influence on the flow coefficient and mixing efficiency.
