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 ms 30 fs. 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.
