Wellposed twophase flow equations with turbulence transport
Abstract
Equations describing the mean dynamics for twophase flow exhibit instabilities corresponding to the physical tendency for such flows to be turbulent. Representation of this effect by means of turbulence transport theory converts the meanflow equations to neutral stability for all perturbation wavenumbers, furnishing a powerful closure constraint for the turbulence transport equations and removing the illposed property previously associated with the simplest of the twophase flow formulations.
