Fiber Deposition Along Airway Walls: Effects of Fiber Cross-Section on Rotational Interception

摘要

Jeffery's equations of motion for ellipsoidal bodies in shear flow are applied to triaxial ellipsoids using numerical integration and modeling. The rotational behaviors of prolate triaxial ellipsoids are compared with ellipsoids of revolution, and the resultant motions are demonstrated to differ significantly. The effects of initial orientations on inhaled fiber motion in human airways are examined, and deposition efficiencies along airway walls are computed. (Copyright (c) 1993 Pergamon Press Ltd.)
