Drop sizes in annular gas‐liquid flows
TL;DR: In this article, the distribution of drop sizes can be characterized by an upper limit, log normal function with only one of the three parameters, the volume median diameter, a strong function of flow conditions.
Abstract: The droplets that appear in annular gas-liquid flows are formed by the eruption of wavelets from the surface of the wall layer. Ninety per cent of the volume of this dispersed liquid is carried by only about 10% of the drops. We find, as suggested by Wicks and Dukler, that the distribution of drop sizes can be characterized by an upper limit, log normal function with only one of the three parameters, the volume median diameter, a strong function of flow conditions. A method for predicting the average diameter is suggested which is consistent with a theoretical interpretation based on a Kelvin-Helmholtz mechanism, whereby the destabilizing force is the pressure variation over the wavelets.

TL;DR: In this article, the authors reviewed the available information on the creation, size and velocity, and removal of drops in annular gas-liquid flow and showed that despite the large number of papers that have been published, there are still some fundamental questions which remain unanswered and there are large gaps in the parameter ranges to be considered.

TL;DR: In this paper, a correlation for entrainment in vertical gas-liquid annular flows is presented, which is based on a balance between the atomization of the wall layer and the rate of deposition of drops.
