TABLE OF CONTENTS In some cases the fluid is neither a pure gas (or vapour) nor a pure liquid, but is a vapour liquid mixture, and it is then necessary to use a correlation for two-phase flow.
The behaviour of fluids in two-phase flow is complex and by no means understood. Of the large literature on the topic mention may be made of the accounts in One Dimensional Two-Phase Flow (Wallis, 1969), Two-Phase Flow and Heat Transfer (Butterworth and Hewitt, 1977), in Two-Phase Flow in Pipelines and Heat Exchangers (Chisholm, 1983) and Emergency Relief Systems for Runaway Reactions and Storage Vessels: A Summary of Multiphase Flow Methods (AIChE, 1992/149) and of the work of Benjaminsen and Miller (1941), Burnell (1947), Lockhart and Martinelli (1949), Pasqua (1953), Schweppe and Foust (1953), O. Baker (1954, 1958), Isbin, Moy and da Cruz (1957), Zaloudek (1961), Fauske (1962, 1963, 1964), Isbin et al. (1962), Fauske and Min (1963), Dukler, Wicks and Clevel and (1964), Levy (1965), F.J.

Work on two-phase flow, particularly in pipelines, has been carried out by the American Institute of Chemical Engineers (AIChE) Design Institute for Multiphase Processing (DIMP). An important distinction in two-phase flow is that...
