Turbulence Decay Intensifies Clustering of Bubbles and Particles
Dante L. Naylor, Zhiyu Yang, Lei Yi +3
Our understanding of inertial particle dynamics in turbulence is mostly based on flows held in a statistically stationary state, a particular regime that differs from many natural…
Hydrodynamic Brachistochrone: Conflicting Paths of Time and Energy Minima within Viscous Media
Ramin Gasimli, Lei Yi, Shrabin Bajracharya +2
We experimentally and theoretically study the hydrodynamic analog of the classical brachistochrone problem: the {\it time-} and {\it energy-minimizing} paths for a spherical partic…
Fluid Dynamical Pathways of Airborne Transmission while Waiting in a Line
Ruixi Lou, Milo van Mooy, Gabriel A Tarditti +2
Waiting in a line (or a queue) is an important, often unavoidable social interaction that occurs frequently in public spaces. Despite its wide prevalence and rich parametric variab…
Shape-Morphing Dynamics of Soft Compliant Membranes for Drag and Turbulence Modulation
Varghese Mathai, Asimanshu Das, Dante L. Naylor +1
We study the kinematics and dynamics of a highly compliant membrane disk placed head-on in a uniform flow. With increasing flow velocity, the membrane deforms nonlinearly into incr…
