Abstract
Two-phase, air-water flew is studied in a horizontal pipe. Water
injection methods are compared to determine an efficient means of
attaining fully developed homogeneous flow. Wall shear forces are
measured directly through flexures attached to a "floating" test
section. The pressure drops are compared to those predicted by the
Lockhart-Martinelli and Chenoweth-Martin correlation schemes . A
computer program is presented for data reduction. For the flow rates
investigated it is concluded that the Lockhart-Martinelli correlation
gives better results than does the Chenoweth-Martin scheme providing
one knows the existing flow pattern. A new method is suggested for
predicting the transition between the Annular and Mist flow regimes.
