A preliminary model of pulmonary airway reopening is developed that includes the physicochemical influence of surfactant under bulk-equilibrium conditions. The airway is modeled following Gaver et al. [J. Fluid. Mech. 319, 25–65 (1996)] as a flexible-walled channel, where walls are membranes under longitudinal tension T, and supported with elasticity E with a stress-free separation distance 2H. The lining fluid has viscosity μ and surface tension γ*. Airway reopening occurs when a semi-infinite bubble of air with pressure Pb* progresses steadily at velocity U and separates the walls. Surfactant exists in the lining fluid (C*) and at the air–liquid interface (Γ*). Bulk equilibrium is assumed (C*=C0) and the kinetic transfer of surfactant between the bulk and interface occurs with a rate k. The equilibrium relationship between Γ* and C* is based upon Henry’s isotherm (Γeq=KC0). The surface tension equation of state, a relationship between γ* and Γ*, is assumed to be linear near Γeq. Marangoni stresses devel...
