The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。

Then the MEMS solenoid type electromagnetic actuating and novel, frictionless and wear-free, and simple structure are designed for fiber-deflecting type MEMS VOA: One of the two coupled single mode fibers is completely fastened in one of the three aligned U-shaped grooves while the deflectable fiber is partially fixed in another groove with a long front section suspending over the wider groove as a cantilever beam. The two fibers, any one for input and the other for output, are well aligned initially so that the insertion loss is very low. Beside the deflectable fiber is a solenoid microactuator with a U-shaped permalloy core attracting a permalloy piece glued on side of the fiber cantilever so that the fiber is deflected and the optical power coupled between the fibers decreased continuously. Using MEMS solenoid as a continuous actuator and the novel structure of VOA are not seen in literature.
