Abstract: The turbulent frictional resistance of dilute polymer solutions can be as low as one-quarter that of the pure solvent. The reduction of drag can be associated with polymer properties and the ...

Abstract: Cavitation in a fluid jet discharged under the surface of a similar fluid was studied using water and dilute solutions of poly(ethylene oxide), a drag-reducing polymer. The addition of a few ...

Abstract: The effects of shape parameters on the performance of water-jet nozzles discharging in air were investigated using a camera specially adapted for jet photography. The boundary-layer developing ...

Abstract: The effect of polymer additives on underwater jet cavitation has been studied using a special camera. Solutions of the drag-reducing additives, polyacrylamide and poly(ethylene oxide), at ...
