TL;DR: In this article , the authors explored the practicality of a two-phase flow model for water droplets in elucidating the blast mitigation mechanism of water droplet, where the main parameter was the layer radius and showed that the critical layer radius was equivalent to the dispersion distance of the detonation products.
Abstract: This study explored the practicality of a two-phase flow model for water droplets in elucidating the blast mitigation mechanism of water droplets. To validate the model, the numerical data were compared with previous experimental results in terms of the evaporation of a single water droplet, and the interaction between the shock/blast waves and water droplets. Results of the validation confirmed good agreement and consistency between both data by combining the existing models for droplet breakup. Next, the blast-mitigation effect of water droplets sprayed around a high explosive was investigated, where the main parameter was the layer radius. A thicker layer further mitigated the blast wave, but there was a limit to the blast-mitigation effect when the layer radius was greater than a critical value. The high-temperature and high-pressure detonation products should interact with the water droplets, which absorb their momentum and energy. The critical layer radius was equivalent to the dispersion distance of the detonation products. To quantitatively understand the blast-mitigation mechanism of water droplets, the transferred energies by drag force, convective heat transfer, radiative heat transfer, and evaporation were computed. A strong correlation between the blast wave strength and the sum of transferred energies by the drag force and convective heat transfer was obtained in the case that the initial diameter of the water droplets was of the order of millimeters.

TL;DR: Wang et al. as mentioned in this paper developed a hydrophilic sessile platform via 3D printing technology to facilely construct the interfacial confined droplets (ICDs) with a designed contact angle by conveniently regulating the droplet volume.
Abstract: The crystallization process in small droplet possessed wide engineering applications in micromaterial fabrication and fine crystal screening. Herein, hydrophilic sessile platform via 3D printing technology was developed to facilely construct the interfacial confined droplets (ICDs) with a designed contact angle by conveniently regulating the droplet volume. The micro-flows inside the droplet were adjusted by controlling the intensity of Marangoni flow and capillary flow within different droplet shapes (i.e., contact angle), which were verified by experimental and simulative results. Especially for the 120° ICD, the micro-flows, achieved by the coordination of Marangoni flow and capillary flow, could convey solutes toward droplet center and harvest a standard cubic crystal at sessile platform center. These results indicated that ICD and sessile platform possessed great potential on high-quality crystal screening and crystallization technique development, which additionally enriched the research strategy on crystal engineering.
