Abstract
The present work studies air-water flows in a commercially available centrifugal pump. The emphasis of this study is to determinate the piezometric head and identify flow patterns downstream and upstream of a centrifugal pump. The experimental hydraulic open loop is fitted with instrumentation to furnish global data on absolute pressure and flow rates. A Shadow Sizer system is also available to furnish local data, including bubble dimension, velocity and frequency.
