| 10. | Finally , compared with the 2d result , the synthetic jet that 3d numerical simulated has a definite direction . the 3d result , however , has a much smaller fluctuation owing to the span - wise instability which created a breakup of coherent vertical structure into smaller scales , it therefore compares more favorably with the measured data in tests
三、三维模拟结果显示合成射流的方向性极佳，与二维模拟相比较，三维数值模拟的速度波动较二维模拟要小，旋涡的相干结构衰弱，这是因为三维模拟考虑了流动的横向不稳定性，这更加接近实际情况。 |
