Differential Geometry of Deterministic Stokesian Dynamics
Sumedh R. Risbud
We present a differential geometric framework for the motion of a non-Brownian particle in the presence of fixed obstacles in a quiescent fluid, in the deterministic Stokesian regi…
Trajectory and distribution of suspended non-Brownian particles moving past a fixed spherical or cylindrical obstacle
Sumedh R. Risbud, German Drazer
We investigate the motion of a suspended non-Brownian sphere past a fixed cylindrical or spherical obstacle in the limit of zero Reynolds number for arbitrary particle-obstacle asp…
Mechanism governing separation in microfluidic pinched flow fractionation devices
Sumedh R. Risbud, German Drazer
We present a computational investigation of the mechanism governing size-based particle separation in microfluidic pinched flow fractionation. We study the behavior of particles mo…
Directional locking in deterministic lateral displacement microfluidic separation systems
Sumedh R. Risbud, German Drazer
We analyze the trajectory of suspended spherical particles moving through a square array of obstacles, in the deterministic limit and at zero Reynolds number. We show that, in the…
Analysis of the trajectory of a sphere moving through a geometric constriction
Sumedh R. Risbud, Mingxiang Luo, Joelle Frechette +1
We present a numerical study of the effect that fluid and particle inertia have on the motion of suspended spherical particles through a geometric constriction to understand analog…
