"Biofluid Mechanics in Lungs and Lung Devices"



ABSTRACT


Biofluid mechanics in the pulmonary system involves multiphase flow phenomena of air-liquid interfaces, surfactants, moving walls, flexible boundaries and a wide range of relevant dimensionless parameter values. This overview of research in our group will include aspects of liquid and surfactant delivery into the lung for purposes of treating hyaline membrane disease of prematurely-born infants and for liquid ventilation, a process of breathing with the lung filled by perfluorocarbon liquid. Dynamics of surface film propagation of surfactant as well as liquid plug propagation in the airways will be discussed in view of both animal and benchtop experiments and related theory. Finally, gas transport in an implantable artificial lung, driven by the heart, will be analyzed for optimizing oxygen and carbon dioxide exchange while minimizing the pressure drop across the bundle of microfibers which make up the device.
