Inertial Migration in Micro-Centrifuge Devices
Samuel Christensen, Marcus Roper
Within microcentrifuge devices, a microfluidic vortex separates larger particles from a heterogeneous suspension using inertial migration, a phenomenon that causes particles to mig…
Approximating pressure-driven Stokes flow using the principle of minimal excess dissipation
Tachin Ruangkriengsin, Marcus Roper
Stokes' equations model microscale fluid flows including the flows of nanoliter-sized fluid samples in lab-on-a-chip systems. Helmholtz's dissipation theorem guarantees that the so…
Fast Asymptotic-Numerical Method For Coarse Mesh Particle Simulation In Channels Of Arbitrary Cross Section
Samuel Christensen, Raymond Chu, Christopher R Anderson +1
Particles traveling through inertial microfluidic devices migrate to focusing streamlines. We present a numerical method that calculates migration velocities of particles in inerti…
Pairwise interactions in inertially-driven one-dimensional microfluidic crystals
Kaitlyn Hood, Marcus Roper
In microfluidic devices, inertia drives particles to focus on a finite number of inertial focusing streamlines. Particles on the same streamline interact to form one-dimensional mi…
Direct Measurement of Particle Inertial Migration in Rectangular Microchannels
Kaitlyn Hood, Soroush Kahkeshani, Dino Di Carlo +1
Particles traveling at high velocities through microfluidic channels migrate from their starting streamlines due to inertial lift forces. Theories predict different scaling laws fo…
Inertial migration of a rigid sphere in three-dimensional Poiseuille flow
Kaitlyn Hood, Sungyon Lee, Marcus Roper
Inertial lift forces are exploited within inertial microfluidic devices to position, segregate, and sort particles or droplets. However the forces and their focusing positions can…
Nuclear flow in a filamentous fungus
Patrick C. Hickey, Anna Simonin, Nick Read +2
The syncytial cells of a filamentous fungus consist of a mass of growing, tube-like hyphae. Each extending tip is fed by a continuous flow of nuclei from the colony interior, pushe…
Summoning the wind: Hydrodynamic cooperation of forcibly ejected fungal spores
Marcus Roper, Agnese Seminara, Ann Cobb +2
The forcibly launched spores of the crop pathogen \emph{Sclerotinia sclerotiorum} must eject through many centimeters of nearly still air to reach the flowers of the plants that th…
