Light-emitting region of cavitation bubble flows generated behind an orifce in a circular pipe has been visualized by optical methods. Xenon gas wsa dissolved in clear water for enhancement of weak emission from cavitation, and its effect on the luminous properties of the flows was investigated. Spacial emission profiles and shadowgraph images of clear water and water-xenon cavitation were obtained by photon counting and and ordinary photographic methods, and compared with each other. It was found that the emission property of the water-xenon cavitation was very similar to that of clear water, and the photographic method was directly apoplicable for the orifice cavitation flow under the enhanced condition.
