A prediction method for entrained liquid fraction in adiabatic gas-liquid flow at high reduced pressure

Abstract

A prediction method for entrained liquid fraction in adiabatic gas-liquid flow at high reduced pressure , the droplet entrainment from the surface of a turbulent film with large-scale waves on its surface is considered. Analysis of the characteristic scales of the process (a probable wavelength of large disturbance, a period of energy-carrying vortices in the gas core, a size of droplets entrained) and the assumption on the possibility of expressing friction factor at the interface through the relative film thickness lead to an equation for the mass flux density of droplets entrained:
