In the lung, the walls of the bronchi are protected by a mucus layer that is constantly renewed and motioned toward the oesopharyngeal region. Its role is to capture the inhaled particles and to remove them from the lung. The mucus layer is submitted to a shear stress by the air flow in the bronchi. The conditions under which it induces a displacement of the mucus, such as during cough, are still not clearly established. Nevertheless, the air--mucus interaction justifies several common chest…

Optimal efficiency of high-frequency chest wall oscillations and links with resistance and compliance in a model of the lung

An idealised HFCWO manipulations applied to a mathematical and numerical model of the biomechanics of the lung are studied, showing that the stress applied to the mucus plays the role of a buffer for the mucUS yield stress, hence reducing the amount of stress needed to mobilize the mucu.



Toward the modeling of mucus draining from the human lung: role of the geometry of the airway tree

This work develops in this work a model of mucus clearance in idealized rigid human bronchial trees and focuses on the interaction between tree geometry, mucus physical properties and amplitude of flow rate in the tree.

Toward the modeling of mucus draining from human lung: role of airways deformation on air-mucus interaction

A quasi-static numerical model of chest physiotherapy based on thorax and lung physiology and on their respective biophysics shows that for secretions to move, air flow has to be high enough to overcome secretion resistance to motion and suggests two a dimensional numbers that depend on lung properties that allow to measure the efficiency and comfort of a manipulation.

New insights into the mechanisms controlling the bronchial mucus balance

The results indicate that the mechanisms controlling the volume of mucus in an airway depend on the localization of the airway in the bronchial region of the lungs, and can improve the understanding and the treatment of pulmonary diseases.

Role of bronchus morphology on mucus mobilization during chest physiotherapy

A numerical model of the biophysics involved in the folding mechanism of the (small) airway walls that leads to "star-shaped" airways sections and the fluid mechanics of air and mucus in such complex cross-sectional geometries shows that mucus standing in the folds can only be mobilized if air flow is kept at high levels.

The role of mucus viscoelasticity in cough clearance.

The relationships between mucus rheology, depth of mucus layer and clearance by simulated cough were examined in a study employing a model plexiglass trachea lined with gels formed from locust bean

Micro- and macrorheology of mucus.

A computational model for expiratory flow.

A mathematical model of maximal expiratory flow was developed and bronchial mechanical properties were obtained from measurements in excised human lungs for the central airways and by extrapolations of these data for the peripheral airways.

Modeling Water Vapor and Heat Transfer in the Normal and the Intubated Airways

To study the dynamics of heat and water transport in the intubated airway, a coupled system of nonlinear equations is solved in airway models with symmetric geometry and anatomically based geometry, and a range of spatially distributed temperature paths is demonstrated.

Techniques for augmenting, when necessary, the normal mucociliary and cough clearance mechanisms of the lungs are not new, but, in more recent years, techniques have been developed which are
