The coalescence phenomenon of drops in liquid/liquid systems is reviewed with particular
focus on its technical relevance and application. Due to the complexity of coalescence, a …

Recent initiatives covered in this review can be divided into three broad categories. The first
category concerns mathematically describing the spray drying process using a plug-flow …

A model is developed for liquid drop impact on a solid surface that captures the thin film gas
flow beneath the drop, even when the film's thickness is below the mean free path in the gas …

Direct numerical simulations are performed to investigate the multiscale flow physics of
binary droplet collision over a wide range of Weber numbers and impact factors. All possible …

Direct numerical simulation of binary droplets collision is done using a conservative level-set
method. The Navier-Stokes and level-set equations are solved using a finite-volume method …

The experimental and numerical investigations of single drop in liquid/liquid extraction
system have been reviewed with particular focus on experimental techniques and …

In the present study the authors compare two different simulation models for the modeling of
droplet collisions. The simulation models are: the Local Front Reconstruction Method …

The physics of droplet collisions involves a wide range of length scales. This poses a
challenge to accurately simulate such flows with standard fixed grid methods due to their …

In this work, droplet–droplet interaction is modelled using a multi-scale approach which
couples multiphase flow simulation using a volume of fluid method to a surface thin film …

Multi-scale simulations have been conducted in order to predict the collision outcome
bouncing versus coalescence in numerical simulations. The flow on the macroscopic scale …
