分岐管内のキャビテーションの観察

抄録

In order to make clear the cavitation aspects in branch ducts, we carefully observed the cavitation for several cavitation numbers σ, radii of curvature on the corners R/b, flow ratios between the upstream duct and the downstream branched duct K, by means of high speed photography and a high speed stereo movie camera, in various kinds of right-angled branch ducts with square cross-section. Typical types of cavitation, their interference, behavior, domain of occurrence are shown.
