چکیده
Abstract This article presents a comparative analysis of flow characteristics behind hydraulic turbine runner in air and water. Swirling with precessing vortex core (PVC) was investigated using laser Doppler anemometer pressure pulsation sensors. The experiments were conducted on aerodynamic hydrodynamic test rigs over wide range operating conditions. Part-load modes operation the Fourier transform pulsations obtained from acoustic features swirling shown for conditions deep partl-load to overload.

Hydraulic researchers had been leading air–water flow studies until the mid-1950s. Since progresses have been dominated by multiphase flow experts despite the relevance of “white water” phenomena to hydraulic engineering. In this lecture the writer reviews the basic mechanisms of air entrainment: singular aeration and interfacial entrainment. The relevant instrumentation and data processing tec...
