Abstract
The paper describes some experimental investigations of the formation and collapse of cavitation bubbles. The experiments were carried on in the high-speed water tunnel of the Hydrodynamics Laboratory of the California Institute of Technology under the sponsorship of the Research and Development Division of the Bureau of Ordnance of the U. S. Navy and the Fluid Mechanics Section of the Office of Naval Research. A detailed study of the formation and collapse of the individual bubbles has been carried on by the use of high-speed motion pictures taken at rates up to 20,000 per sec. From these records calculations have been made of rate of formation and collapse of the bubbles. Deductions have been drawn from these results concerning the physical mechanism of the cavitation phenomenon.

© 1948 ASME. Contributed by the Hydraulic Division and presented at the Annual Meeting, Atlantic City, N. J., December 1-5, 1947, of the American Society of Mechanical Engineers. This program is being carried on in the Hydrodynamics Laboratory of the California Institute of Technology as a part of a research project which is being sponsored jointly by the Research and Development Division of the Bureau of Ordnance and the Fluid Mechanics Section of the Office of naval Research, both of the U.S. Navy. Practically every member of the laboratory staff has contributed substantially to the experiments which furnish the basis of this paper. In addition, special appreciation is due to Haskell Shapiro and his staff who are responsible for the development and operation of the high-speed flash lamps, and to Hugh S. Bell and Donald Peterson for the photography and particularly for the development and perfection of methods of making projectionable motion-picture-film strips from the original high-speed pictures.Attached Files
