摘　　要：针对安装了激振器的NACA0012二维翼型,采用数值模拟的方式对零质量射流技术进行研究。流场解算器采用了中国航空工业空气动力研究院计算所自主研发的ENSMB V1.2计算平台。计算结果给出了湍流模型对零质量射流数值模拟技术的影响,并且分析了激振器参数对翼型气动力特性的影响规律。In this paper, an investigation on the numerical simulation of ＂ zero- mass＂ jets and their impact on the aerodynamic characteristics of the NACA0012 airfoil is presented. The solver is called ENSMB developed by Chinese Aerodynamic Research Institute of Aeronautics and version 1.2 of it is utilized. The effects of some different turbulence models are explored in the computations. Then we pay attentions to the effects of the jet placement, the jet peak suction and blowing velocities, oscillation frequency on the time histories of the sectional lift, drag and moment coefficients.
