Measurement of the Velocity Field and Void Fraction in a Planar Plunging Jet

Abstract

This paper presents experimental data for a planar plunging liquid jet. Local data, including the void fraction, and the mean and turbulent bubble and liquid velocities were obtained using an impedance probe and a Laser Doppler Anemometer (LDA) - Fiber optics Laser Doppler Anemometer (FPDA) system. A dual element conductivity probe was also used to measure the spatial distribution of the local void fraction. The turbulence of the plunging jet was parametrically controlled using a special designed nozzle.
