Simultaneous Measurements of Two Phases Using an Optical Probe

Abstract

Accurate simultaneous measurement of multiple parameters in two-phase gas-liquid flows remains a significant experimental challenge. Optical probes offer a non-intrusive approach that can provide local measurements of phase fraction, bubble velocity, bubble frequency, and bubble chord length distribution. This work describes the application of an advanced optical probe technique for simultaneous measurements of two phases in gas-liquid flows.

The optical probe methodology enables the simultaneous acquisition of information about both gas and liquid phases at a measurement point, providing complementary data that improves the characterisation of two-phase flow behaviour. The technique is validated and applied to characterise bubble properties in gas-liquid systems, demonstrating its capability to resolve local phase distribution and bubble dynamics with high spatial resolution. The approach provides a valuable experimental tool for studying gas-liquid hydrodynamics in stirred tanks and other multiphase process equipment, with particular value for validating computational fluid dynamics (CFD) models of complex two-phase flows.
