Paper Abstract

High speed liquid flows within glass nozzles of very small geometry and the resulting jets leaving those nozzles were studied. Due to the high flow velocity cavitation films are generated at the sharp inlet of the nozzles, they collapse and break up into bubbles further downstream. These bubbles can serve as tracers for a velocimeter based on a cross-correlation method. Using this technique we succeeded to measure velocities inside and outside the nozzle of up to several hundred meters per second.
