Second, numerical simulation and qualitative analysis has been done for the synthetic jet flow field in different cases (different phase, amplitude and frequency), and gained many conclusions which are helpful for designing the synthetic jet actuator.

• 二、对不同驱动频率，振动膜速度幅值以及激励器的结构对合成射流的影响分别进行数值计算和定性分析，得到了大量有助于合成射流激励器设计的结论。
