Spatio-Temporal Instabilities of Blood Flow in a Model Capillary Network
Mathieu Alonzo, Nathaniel J. Karst, Thomas Podgorski +2
We present experimental evidence of multiple blood flow configurations in a relatively simple microfluidic network under constant inlet conditions. We provide evidence of multistab…
Analytic instability thresholds in folded Kerr resonators of arbitrary finesse
William J. Firth, John B. Geddes, Nathaniel J. Karst +1
We present analytic threshold formulae applicable to both dispersive (time-domain) and diffractive (pattern-forming) instabilities in Fabry-Perot Kerr cavities of arbitrary finesse…
Observations of spontaneous oscillations in simple two-fluid networks
Brian D. Storey, Deborah V. Hellen, Nathaniel J. Karst +1
We investigate the laminar flow of two-fluid mixtures inside a simple network of inter-connected tubes. The fluid system is comprised of two miscible Newtonian fluids of different…
Spontaneous oscillations in simple fluid networks
Nathaniel J. Karst, Brian D. Storey, John B. Geddes
Nonlinear phenomena including multiple equilibria and spontaneous oscillations are common in fluid networks containing either multiple phases or constituent flows. In many systems,…
Laminar flow of two miscible fluids in a simple network
Casey M. Karst, Brian D. Storey, John B. Geddes
When a fluid comprised of multiple phases or constituents flows through a network, non-linear phenomena such as multiple stable equilibrium states and spontaneous oscillations can…
Bistability in a simple fluid network due to viscosity contrast
John B. Geddes, Brian D. Storey, David Gardner +1
We study the existence of multiple equilibrium states in a simple fluid network using Newtonian fluids and laminar flow. We demonstrate theoretically the presence of hysteresis and…
