Universal mapping of drop impact spreading from wetting to Leidenfrost regimes
Shushan Hu, Nan Hu, Zirui Li +3
We establish a universal mapping between the maximum spreading of a drop under wetting and Leidenfrost impact conditions from an energy-dissipation perspective, with the latter fea…
Understanding the Theory--Experiment Discrepancy in Pressure Drop of Dilute Polymer Solutions in Channel Flows
Nan Hu, Jonghyun Hwang, Evgeniy Boyko +1
For decades researchers have experimentally observed that the flow of dilute viscoelastic polymer solutions through contraction or contraction--expansion channels yields results at…
Semi-analytical model for the rising sheet generated by droplet-pair impact
Shushan Hu, Liwu Fan, Nan Hu
When two low-Ohnesorge-number drops impact a dry substrate simultaneously, their spreading lamellae collide and lift a free-standing vertical sheet. The sheet grows by inertial fee…
Revealing Actual Viscoelastic Relaxation Times in Capillary Breakup
Nan Hu, Jonghyun Hwang, Tachin Ruangkriengsin +1
We use experiments and theory to elucidate the size effect in capillary breakup rheometry, where pre-stretching in the visco-capillary stage causes the apparent relaxation time to…
Close-contact melting on hydrophobic textured surfaces: Confinement and meniscus effects
Nan Hu, Liwu Fan, Xiang Gao +1
We investigate the dynamics of close-contact melting (CCM) on gas-trapped hydrophobic surfaces, with specific focus on the effects of geometrical confinement and the liquid-air men…
