Global Thermal Modeling of Lung Heat Transfer with Blood Perfusion
Résumé
Thermal models often consider low-frequency approximations and are largely based upon RC circuits. If temperature fluctuations are non-negligible, a more accurate model is needed and is proposed through thermal two-port network which is direct extension of the heat equation into matrix formalism. As blood flow plays a major role for heat transfers in biological tissue, a second model is obtained from the bio-heat equation. These two type of models are combined into a global thermal modeling of human lung by considering blood perfusion.
