Development of actively-controlled counter driver shock tube capable of precise flow control

我们已经开发了一个激波管与两个计数器驱动器的条件，其中每一个可以独立设置。从三个标准，（1）有效隔膜破裂时间和相关的冲击波形成距离，（2）压力损失和流量均匀性，以及（3）在隔膜破裂控制的时间抖动，采用评估驱动器的性能。结果，采用了使用气动缸的装置，从而进行了包括激波-湍流相互作用的演示实验。

We have developed a shock tube with two counter drivers the condition to each of which can be set independently. From three criteria, (1) the effective diaphragm rupture time and associated shock wave formation distance, (2) pressure loss and flow uniformity, and (3) temporal jitter in the diaphragm rupture control were adopted to evaluate the driver performance. As the result, the device using an pneumatic cylinder was employed, thereby demonstration experiments including those for shock wave-turbulence interaction were conducted.
