英文摘要	Conference Name:6th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment. Conference Address: Xiamen, China. Time:April 26, 2012 - April 29, 2012.; The Chinese Optical Society (COS); Inst. Opt. Electron. (IOE), Chinese Acad. Sci. (CAS); Wake vortex behind an aircraft would introduce great hazard to the following aircraft and threaten to the flight safety. Generic model using two rectangular airfoils was employed for generating wake vortex system to investigate the method of wake vortex alliviation. The investigation was carried out in a water towing tank equipt with Particle Image Velocimetry system. Characteristics of double-vortex flow were analyzed for selected cases, proving that the intensity of the vortex is reduced with respect to the interaction between the wake vortices. The study exhibited that the R-L instability was most effectively triggered with parameter combinations of 伪1= 10掳, 伪2=8掳 and b=50mm respectively. As a result, the circulation of the wake vortices was alleviated by nearly 40% accordingly. 漏 2012 SPIE.
