Abstract

The measurements of bubble parameters in flashing flows are presented in this paper. Four-sensor conductivity probes are used to measure the bubble duration, chord length, and number frequency of spherical, cap, and slug bubbles. The distributions of each parameters are plotted and observed to be positively-skewed. Parametric studies are performed to understand the effects of pressure and mass flux on the distributions of bubble durations, chord lengths, and number frequencies. A multivariate plot is also included to show the interdependence of bubble number frequency, chord length, and void fraction. This work aims to extend the application of the conductivity probe to the direct measurement of two-phase properties and provide additional information useful to the validation of high-fidelity two-phase simulations.
