Heat and Mass Transfer in the Human Respiratory Tract at Hyperbaric Pressures.
Abstract
The objective of the project was to mathematically model the heat loss process that occurs in the respiratory tracts under deep ocean saturation diving conditions. This was approximated by determining the heat transfer characteristics of a branching scale model of the first two branches of the human lower respiratory tract. Heat transfer coefficients were obtained for a range of respiratory rates and respiratory gas mixtures for simulated ocean depths 0 to 1000 feet. These heat transfer coefficients were used to predict the heat loss from the respiratory tract of a diver by the successive application of the branching model, appropriately scaled, to simulate progressive units of the lung's anatomical configuration.
