FLOW FIELD VISUALIZATION DEVICE, FLOW FIELD OBSERVATION METHOD, AND PLASMA GENERATOR

摘要

A flow field visualization device includes a chamber, a power supply, at least one pair of electrodes, and at least two high-speed cameras. The power supply outputs a voltage for plasma generation, and the pair of electrodes is disposed in the chamber. The pair of electrodes includes a first electrode and a second electrode. The first electrode has a plurality of first tips, the second electrode has a plurality of second tips, and the first tips and the second tips are aligned with each other. The pair of electrodes generates a periodically densely distributed plasma by exciting a gas in the chamber through the voltage from the power supply. The high-speed cameras are disposed outside the chamber and are positioned in different directions corresponding to the pair of electrodes in order to capture images of different dimensions.
