New York: McGraw-Hill. 1 Need for a phenomenological understanding The one-dimensional analysis and the correlations for frictional pressure drop and void fraction (presented in Chapter 1) have been widely used as a starting point for engineering designs. However, these correlations have the handicap that the structure of the phase boundaries is ignored. As a consequence, they often give results which are only a rough approximation and overlook phenomena which could be of first-order importance in understanding the behavior of a system.

In this pattern, all of the liquid moves along the bottom of the pipe. 2 Flow regimes in horizontal pipes 29 At very low gas and liquid velocities the interface is smooth. However, at larger gas velocities waves appear. Three types of waves have been identified: Jeffreys waves, Kelvin–Helmholtz waves and roll waves. The first interfacial disturbances observed in air–water flow with increasing gas velocity are Jeffreys waves (Jeffreys, 1925) for which a balance exists between the energy fed to the waves by the air flow and dissipation in the liquid (Hanratty & Engen, 1957; Cohen & Hanratty, 1965; Andritsos & Hanratty, 1987).

The use of single-phase relations for τW with ρH substituted for ρ and a viscosity which is a combination of the liquid and gas viscosities is not substantiated. An appreciable slip can exist between the phases, so the equating of α to x can be incorrect and lead to errors in calculating the contribution of the pressure drop associated with hydrostatic head. Also, the assumption of equilibrium between vapor and liquid phases can be in error. 1 Basic equations The separated flow model differs from the homogeneous model by recognizing that the velocities of the two phases are usually different.
