The wetting and evaporation dynamics of sessile droplets have gained considerable
attention over the last few years due to their relevance to many practical applications …

An air bubble rising in a non-Newtonian fluid (shear thinning/thickening) has been
numerically studied using a volume-of-fluid (VoF) approach in the axisymmetric regime. The …

The dynamics of an air bubble rising in a quiescent shear-thinning fluid modelled using a
simplified Carreau-Yasuda rheological model is investigated numerically and …

The coalescence dynamics of ethanol drops injected from a needle on the free-surface of an
ethanol pool maintained at a higher temperature than the drop is experimentally studied …

The dynamics of a nonspherical droplet falling in air is investigated via three-dimensional
numerical simulations of the Navier-Stokes and continuity equations. The main focus of this …

Thermal stratification is of great concern for liquid propellant storage tanks of space vehicles.
The present study's primary objective is to better understand the bubble dynamics on …

The motion of a surfactant-laden viscous droplet in the presence of non-isothermal
Poiseuille flow is studied analytically and numerically. Specifically, the focus of the present …

Despite its significance in droplet-based microfluidic technologies with the use of thermal
stimuli and surfactants, coupling effects of thermal-and surfactant-induced Marangoni …

Self-rewetting fluids (SRFs), such as aqueous solutions of long-chain alcohols, show
anomalous nonlinear (quadratic) variations of surface tension with temperature involving a …

In this paper, we simulate the effects of confinement on three-dimensional bubble dynamics
in a square duct. A systematic study of three confinement ratios, four Bond numbers and two …
