▪ Abstract Almost all vessels carrying fluids within the body are flexible, and interactions
between an internal flow and wall deformation often underlie a vessel's biological function or …

The delicate structure of the lung epithelium makes it susceptible to surface tension induced
injury. For example, the cyclic reopening of collapsed and/or fluid-filled airways during the …

We describe a microfabricated airway system integrated with computerized air–liquid two-
phase microfluidics that enables on-chip engineering of human airway epithelia and precise …

Airway collapse and reopening due to mechanical ventilation exerts mechanical stress on
airway walls and injures surfactant-compromised lungs. The reopening of a collapsed …

Growth of complex dendritic fingers at the interface of air and a viscous fluid in the narrow
gap between two parallel plates is an archetypical problem of pattern formation. We find a …

The interfacial convection in multilayer systems is a widespread phenomenon that is of great
importance in numerous branches of technology, including chemical engineering, space …

We study the viscous-fingering instability in a radial Hele-Shaw cell in which the top
boundary has been replaced by a thin elastic sheet. The introduction of wall elasticity delays …

The reduction of tidal volume during mechanical ventilation has been shown to reduce
mortality of patients with acute respiratory distress syndrome, but epithelial cell injury can …

Propagation of a viscous fluid beneath an elastic sheet is controlled by local dynamics at the
peeling front, in close analogy with the capillary-driven spreading of drops over a precursor …

Recent experiments by Pihler-Puzovic et al.(Phys. Rev. Lett., vol. 108, 2012, article 074502)
have shown that the onset of viscous fingering in circular Hele-Shaw cells in which an air …
