摘要
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.
Flow visualization technology with particle image velocimetry system was applied in the paper to study the mixing flowfield of gas-gas injector.The method of tracing two different flows separately was adopted and three typical injectors,such as coaxial shear injector,coaxial swirl injector and triple impinging injector,were selected to conduct out a series of tests.The experimental results validate the way to trace the two flows separately credible and show the different mixing mechanisms of three typical injectors with axial and cross-section images,which reveal the major impact factors of mixing process and distribution features of mixing flowfield.
