设计了一种侧喷型合成射流器,考察了射流器喷口结构尺寸对射流速度的影响,计算了不同喷口宽度下的动量系数,确定了喷口的最优尺寸,并在攻角为23°的NACA0015翼型进行了数值仿真模拟。结果表明,合成射流器可以有效的抑制边界层流动分离。同时设计了器件的加工工艺流程并完成了器件的加工。
A side jet type synthetic jet was designed. The influence of jet nozzle structure size on the jet velocity was investigated. The momentum coefficient at different jet width was calculated, the optimum size of the jet was determined. At the angle of attack of 23 ° NACA0015 airfoil numerical simulation. The results show that the synthetic jet can effectively suppress the boundary layer flow separation. At the same time designed the device processing process and completed the device processing.
