Abstract
A visualization device for a flow field includes a chamber, a power supply, at least one pair of electrodes, and at least one flow field observation module. The flow field observation module includes a high-speed camera, a light detecting component, and a light filter component. The power supply outputs a voltage to generate a plasma, and the pair of electrodes is disposed in the chamber. The flow field observation module is disposed outside the chamber and captures an image of a fluid particle excited by the plasma toward the chamber. The light filter component is disposed between the high-speed camera and the chamber. The light detecting component obtains a light information within the chamber and sends the light information to the light filter component.
