Abstract:
1. A fluid body flow visualization device for visualizing a flow of a fluid body around a measuring object, the device comprising: a fluid body supply unit operable to supply a first fluid body as a tracer from a nozzle hole to a flow field of a second fluid body, the fluid body supply unit including a nozzle array in which the nozzle hole is arrayed with a plurality of nozzle holes, with each of the nozzle holes supplying the first fluid body to the flow field; a laser beam supply unit operable to irradiate the flow field with a laser beam having a wavelength optically absorbed by the first fluid body in a manner such that the laser beam traverses the flow field, and operable to control an irradiation position of the laser beam in a manner such that the flow field is scanned; a beam receiving unit operable to receive the laser beam which has traversed the flow field; and a processing unit operable to visualize a flow of the second fluid body in the flow field using a scan intensity signal of the received laser beam; the nozzle array being provided so as to be orthogonal to a direction in which the laser beam traverses the flow field; and the flow field is scanned with the laser beam in an array direction of the nozzle holes.
