Vertically-Upward Two-Phase Flow in an Annulus

Abstract

This describes an experimental study of pressure drop in vertically two phase flow in annulus. An experimental rig was designed and built to pressure drop and observe flow regime for air mixtures in a vertical 48.3 x 74.0 annulus. Measured pressure drop is compared to that predicted by the of Duns Ros Hagedorn Brown Orkiszewski Aziz et al. (1972). Beggs Brill (1973) and Caetano et al. These correlations are also applied to the experimental results of Gaither et al. (1963) who measured pressure drop for water gas mixtures through a 1"x 2" (25 x 50 annulus inside a ft (305m) deep test well.
