Seeing new depths: Three-dimensional flow of a free-swimming alga
Gregorius Pradipta, Wanho Lee, Van Tran +8
A swimming microorganism stirs the surrounding fluid, creating a flow field that governs not only its locomotion and nutrient uptake, but also its interactions with other microorga…
Inertia-Dilatancy Interplay Governs Shear-Thickening Drop Impact
Anahita Mobaseri, Leonardo Gordillo, Charles Burton +5
Combining high-speed photography with direct force measurements, we investigate the impact dynamics of drops of cornstarch-water mixtures -- a premier example of shear-thickening f…
Dynamics of rotating helices in viscous fluid
Chijing Zang, Luke Omodt, Moumita Dasgupta +1
We investigate the dynamics of a pair of rigid rotating helices in a viscous fluid, as a model for bacterial flagellar bundle and a prototype of microfluidic pumps. Combining exper…
Maximum spreading of impacting shear-thinning and shear-thickening drops
Anahita Mobaseri, Satish Kumar, Xiang Cheng
The maximum spreading of an impacting liquid drop is a key metric for characterizing the fundamental fluid process of drop impact. While extensively studied for Newtonian liquids,…
