摘要

基于两种不同的射流孔宽度及宽广的射流参数范围

对扇形射流垂直入射至主流时进行了空气动力学试验研究.测量了不同射流参数下管内的轴向压力分布

并且对不同结构的射流槽的试验结果进行了比较.结果表明:射流出口为锐边时

压力峰值出现在射流下游的稀薄区域; 射流出口为圆边时

压力峰值出现在射流入射区.最后

测量了垂直入射时的局部水力损失

发现在高流速比下

水力损失的试验结果明显低于理论计算值.

Abstract

Experiment was conducted on aerodynamics of radial slot jet normally injecting into ducted flow for two slots with different width. The distributions of the axial pressure in the tube under different injection parameters were measured. The experimental data of the different structure of the slots were also analyzed. The results show that the pressure peak was observed in the rarefaction zone when the injection outlet edge was sharp and also observed in the injection region when the injection outlet edge was round. In addition

local hydraulic losses of normal injection were measured and it is found that the hydraulic losses predicted were significantly higher than that measured at high flow velocity ratio.
