Wisp-like structures in vertical gas-liquid pipe flow revealed by wire mesh sensor studies

Perez, V. H.; Azzopardi, B. J.; Kaji, R.; Da Silva, M. J.; Beyer, M.; Hampel, U.

A conductance Wire Mesh Sensor system has been employed on a vertical 67 mm diameter pipe with the up flow of air and water mixtures. The measuring system provides time and cross-sectionally resolved information about the spatial distribution of the phases. Statistical information can be extracted and used to identify flow patterns. The fully resolved data has revealed a hitherto unreported structure has been seen in churn flow which could be linked to the wisps in wispy-annular flow.

Keywords: gas-liquid two-phase flow; wire mesh sensor
