Air-Water Flow Measurements with Intrusive, Phase-Detection Probes: Can We Improve Their Interpretation?

Abstract

Interest in air-water flows has not diminished in recent years, as evident by the number of associated papers published in the Journal of Hydraulic Engineering and other journals, such as the Journal of Hydraulic Research, the International Journal of Multiphase Flow and the Journal of Fluids Engineering. The writer believes that a particularly important issue is the often inadequate or incomplete interpretation of air-water flow instrumentation by hydraulic engineers and researchers. The present Forum article briefly comments of the several common techniques for measuring air-water flows by means of intrusive phase detection probes, and it describes a basic data processing method that readily yields expanded information on air-water flow properties.
