Droplet Impact on Microparticle Raft: Wettability, density and size govern splashing and microplastic ejection from rafts under raindrop impact
Muhammad Hamza Iqbal, Alfonso Arturo Castrejón-Pita, José Rafael Castrejón-Pita +1
Raindrop impact on the ocean has been proposed as a mechanism for microplastic transfer from seawater to the atmosphere, yet the interfacial dynamics governing particle ejection fr…
Fast droplet impact onto slowly moving deep pools
Thomas C. Sykes, Luke F. L. Alventosa, J. Rafael Castrejon-Pita +3
When a fast droplet impacts a pool, the resulting ejecta sheet dynamics determine the final impact outcome. At low Capillary numbers, the ejecta sheet remains separate from a deep…
Predicting liquid properties and behavior via droplet pinch-off and machine learning
Jingtao Wang, Qiwei Chen, C Ricardo Constante-Amores +3
Here we demonstrate that the time-evolving interface observed during droplet formation, and consequently the resulting morphology nearing pinch-off, encode sufficient physical info…
Impact of droplets onto surfactant-laden thin liquid films
C. R. Constante-Amores, L. Kahouadji, S. Shin +5
We study the effect of insoluble surfactants on the impact of surfactant-free droplets on surfactant-laden thin liquid films via a fully three-dimensional direct numerical simulati…
Role of surfactant-induced Marangoni stresses in retracting liquid sheets
C. R. Constante-Amores, J. Chergui, S. Shin +3
In this work, we study the effect of insoluble surfactants on the three-dimensional rim-driven retraction dynamics of thin water sheets in air. We employ an interface-tracking/leve…
Surface jets and internal mixing during the coalescence of impacting and sessile droplets
Thomas C. Sykes, Alfonso A. Castrejón-Pita, J. Rafael Castrejón-Pita +4
The internal dynamics during the coalescence of a sessile droplet and a subsequently deposited impacting droplet, with either identical or distinct surface tension, is studied expe…
