| Zusammenfassung | The flow in cavitating Venturi nozzles (CV) is a long time subject of experimental as well as numerical investigations. If the pressure decreases due to the local acceleration to the respective vapour pressure, a chocked flow condition similar to the well-known critical flow Venturi-nozzles (CFVN) develops. For the purpose of gaining further insight into the chocked flow condition with respect to liquid flow measurement, high-speed camera investigations of a transparent Herschel Venturi-tube configuration were performed. Together with pressure and flow rate measurements, they demonstrated the overall stable flow behavior under chocked conditions. With additional numerical investigations, phenomena during the onset of the chocked condition were clarified. Furthermore, a simple correlation for the calculation of the actual flow rate during chocked condition, as well as a temperature correction is proposed. |
