Influence of Gas Content and Polyethylene Oxide Additive upon Confined Jet Cavitation in Water.

Abstract

Desinent cavitation data were obtained for confined water jets generated by a 5.08 cm (2 in.) diameter sharp-edged orifice and a contoured nozzle of the same diameter. Data were acquired over a range of total air content from 2.0 to 12.0 parts per million (mole basis) in water and a water polyox (WSR-301) solution of 100 parts per million (weight basis). The jet velocity was constant at 9.1 m/s (30 f/s). In general the polyox caused a reduction in the desinent cavitation index and the reduction increased with air content. However, below an air content of 4.0 ppm the desinent cavitation index is apparently independent of air content.
