Viscoelasticity reduces the droplet size in mucosalivary film fragmentation during intense respiratory events
Mogeng Li, Youssef Saade, Stéphane Zaleski +3
We examine the fundamental fluid dynamical mechanisms dictating the generation of bioaerosols in the human trachea during intense respiratory events such as coughing and sneezing,…

Marangoni flow driven hysteresis and azimuthal symmetry breaking in evaporating binary droplets
Duarte Rocha, Detlef Lohse, Christian Diddens
The non-uniform evaporation rate at the liquid-gas interface of binary droplets induces solutal Marangoni flows. In glycerol-water mixtures (positive Marangoni number, where the mo…

Pinning induced motion and internal flow in neighbouring evaporating multi-component drops
Pim J. Dekker, Marjolein N. van der Linden, Detlef Lohse
The evaporation of multi-component sessile droplets is key in many physicochemical applications such as inkjet printing, spray cooling, and micro-fabrication. Past fundamental rese…
