Breath Figures: Nucleation, Growth, Coalescence, and the Size Distribution of Droplets

TL;DR

This paper investigates the size distribution of droplets in breath figures, emphasizing the importance of growth mechanisms to accurately describe their evolution and connect nucleation to overall distribution features.

Contribution

It introduces a framework that explicitly incorporates droplet growth mechanisms, linking nucleation processes to the evolution of droplet size distributions.

Findings

Growth mechanisms are essential for accurate size distribution modeling

A connection between nucleation and distribution evolution is established

Scaling theories must consider droplet growth dynamics

Abstract

The analysis of the size distribution of droplets condensing on a substrate (breath figures) is a test ground for scaling theories. Here, we show that a faithful description of these distributions must explicitly deal with the growth mechanisms of the droplets. This finding establishes a gateway connecting nucleation and growth of the smallest droplets on surfaces to gross features of the evolution of the droplet size distribution.
