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…
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…
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…
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…
