Evaporation of thin liquid droplets on heated surfaces: theory versus experiment
TL;DR: In this article, a mathematical model is developed based on the assumption that the droplet surface has uniform mean curvature and the contact line is pinned during evaporation, and the dynamics of liquid-vapor interface and the temperature profiles at the foil are shown to be in good agreement with the experimental data.

Energy analysis of secondary droplet atomization schemes
TL;DR: In this paper, the energy analysis of the secondary atomization of droplets with various component compositions is presented, and the authors show that the least energy consuming scheme is the one involving droplets colliding with each other and the most effective one in terms of fine aerosol production is the scheme with the micro-explosive droplet breakup.

Local heating effect on thermal Marangoni flow and heat transfer characteristics of an evaporating droplet
TL;DR: In this article , the authors applied the dynamic mesh method to simulate the behaviors of the liquid-air interface during evaporation, and found that the flow transition inside the droplet appeared in the early stages of the process and occurred owing to the temperature variation at the liquid air interface, resulting in surface tension gradients.

Local mass flux and pinning behavior of an evaporating droplet on heated aluminum surfaces
TL;DR: In this article, the characteristics of pinning behaviors and local mass flux variations during droplet evaporation at different surface temperatures ranging from 22.5°C to 80°C were investigated.

Solid–Liquid Interface Temperature Measurement of Evaporating Droplet Using Thermoresponsive Polymer Aqueous Solution
TL;DR: In this article, the authors measured the solid-liquid interface temperature of an evaporating droplet on a heated surface using a thermoresponsive polymer and found that the reflectance of a poly(N-isopropylacrylamide) solution decreased after the droplet deposition.

Analysis of the effects of Marangoni stresses on the microflow in an evaporating sessile droplet.
Hua Hu,Ronald G. Larson +1 more
TL;DR: It is found that surfactant contamination, at a surface concentration as small as 300 molecules/microm(2), can almost entirely suppress the Marangoni flow in the evaporating droplet.

Self‐Ordering of Cell Arrangement of Anodic Porous Alumina Formed in Sulfuric Acid Solution
TL;DR: In this paper, self-ordering of the cell arrangement of the porous structure of anodic alumina has been studied in a sulfuric acid solution, and a highly ordered structure was obtained under anodization at a constant potential of 25 to 27 V.

On the Growth of Highly Ordered Pores in Anodized Aluminum Oxide
TL;DR: In this paper, it was shown that hexagonally ordered domain structures can be formed in anodic alumina films by repeated anodization and stripping of the porous oxide, and the domain size is a linear function of time and increases with temperature.
