TL;DR: In this article, the shape and velocity of the slug, the velocity distribution and the distribution of local wall shear stress were computed and compared favourably with the published experimental findings.

TL;DR: In this article, the authors used the volume of fluid method implemented in the commercial CFD package, Fluent, for a numerical study of long gas bubbles inside capillaries, where the velocity and bubble profile were obtained as functions of capillary number.

TL;DR: In this article, an attempt is made to model slug flow inside square capillaries containing Newtonian liquids and a comprehensive description of such flow is obtained and a comparative study is conducted.

TL;DR: In this article, an attempt is made to model the slug flow ultrafiltration process using the volume of fluid (VOF) method with the aim of understanding and quantifying the details of the permeate flux enhancement resulting from gas sparging.

TL;DR: In this paper, the authors compared the effect of gas bubbles on the performance of two-phase cross-flow ultrafiltration with different membrane modules (in particular, tubular and hollow fibre membrane modules).
