研究气-气喷注器气流流动混合过程,基于粒子图像测速仪(PIV)实验系统,采用对两股气流分别示踪的方法,对三种典型结构的气-气喷注器混合场开展了实验研究.实验结果验证了这种实验方案的可行性,结合轴截面和横截面的流场分布测量,得到了同轴离心式、同轴直流式、互击式气-气喷注器气流混合过程的主要作用因素和混合场的分布特征.
The gas-air injector flow mixing process was studied. Based on the particle image velocimetry (PIV) experimental system, three typical gas-air injector mixing fields Experimental results verify the feasibility of this experimental scheme, combined with the measurement of the flow field distribution of the axial section and the cross section, the coaxial centrifugal, coaxial direct-flow, reciprocal gas-air injector airflow mixing The main role of the process and the distribution of mixed field characteristics.
