TLDR
In this article, a new expression for the slug mixing length as a function of the film Froude number was proposed, which was shown that the Hubbard and Dukler model for mixing length is inadequate.Abstract:
A definition is given for a Froude number in the liquid film ahead of the slug and it is seen that slug characteristics are strongly influenced by the Froude number. The mechanisms in the mixing zone of the slug are described in detail and are shown to be a function of the film Froude number. It is shown that the Hubbard and Dukler model for mixing length is inadequate. A new expression is proposed for the slug mixing length as a function of the film Froude number.read more

Mass Transfer Coefficient Measurement in Water/Oil/Gas Multiphase Flow
TL;DR: In this paper, a relationship between the average mass transfer coefficient in full pipe flow and slug flow was developed, which was due to the existence of oil phase, which decreased the ionic mass transfer diffusion coefficient.
