Stretching and breaking of particles in compressible random flows
Dipankar Roy, Marco Martins Afonso, Jason R. Picardo +1
A key feature of turbulent suspensions that involve floating particles on the surface or inertial particles in the bulk is the compressibility of the effective particle-phase veloc…
Morphology of mucus films in lung airways: secretion and ciliary evacuation
Swarnaditya Hazra, Jason R. Picardo
Lung airways are lined by a film of mucus which protects the epithelium from inhaled particles. To maintain a uniform coating, the mucus that is secreted into airways must be distr…
Bioluminescence in turbulence: intermittent straining lights up dinoflagellates
Praphul Kumar, Jason R. Picardo
Dinoflagellates are marine phytoplankton that emit flashes of light in response to flow-induced deformation; they are responsible for illuminating breaking-waves, wakes of ships, a…
How hydrodynamic interactions alter polymer stretching in turbulence
Aditya Ganesh, Dario Vincenzi, Ranganathan Prabhakar +1
Hydrodynamic interactions (HI) between segments of a polymer have long been known to strongly affect polymer stretching in laminar viscometric flows. Yet the role of HI in fluctuat…
Deriving thin-film averaged equations using computer algebra
Swarnaditya Hazra, Jason R. Picardo
We demonstrate the use of computer algebra for facilitating the derivation of thin film reduced-order models. We focus on the weighted residual integral boundary layer (WRIBL) meth…
Turbulent stretching of dumbbells with hydrodynamic interactions: an analytical study
Jason R. Picardo, Dario Vincenzi
We study the stretching of an elastic dumbbell in a turbulent flow, with the aim of understanding and quantifying the effect of hydrodynamic interactions (HI) between the beads of…
Active waves from non-reciprocity and cytoplasmic exchange
Jason R. Picardo, V. Jemseena, K. Vijay Kumar
Pattern formation in active biological matter typically arises from the feedback between chemical concentration fields and mechanical stresses. The actomyosin cortex of cells is an…
Probabilistic plugging of airways by sliding mucus films
Swarnaditya Hazra, Jason R. Picardo
When do mucus films plug lung airways? Using reduced-order simulations of a large ensemble of randomly perturbed films, we show that the answer is not determined by just the film's…
Aerosol deposition in mucus-lined ciliated airways
Swarnaditya Hazra, Jason R. Picardo
We study the transport and deposition of inhaled aerosols in a mid-generation, mucus-lined lung airway, with the aim of understanding if and how airborne particles can avoid the mu…
