Abstract:

The paper is a report of an experimental investigation of the dissolving of gas nuclei small gas bubbles in turbulently flowing water in a pipe. The rate of dissolving is important in a circulating water tunnel because it determines whether or not cavitation produced nuclei reach a small size to produce tensile strength in the water, increase the cavitation inception level, and affect the results of a cavitation test. The rate of dissolving is greatly affected by the presence of surface films that form about gas nuclei from trace organic materials dissolved in the water. Author
