Abstract
Adiabatic concurrent vertical and horizontal two-phase flow of air and water through narrow rectangular channels, gap widths 1 and 2 mm, was investigated. This study involved the observation of flow using a charge coupled device (CCD) camera and flow regimes were determined by examining the video images. A comparison of the resulting data was made with previous experimental data and also to existing transition criteria. There were four flow regimes and three transition regions observed for vertical flow and five flow regimes and three transition regions for horizontal flow.
