Abstract
There have been many attempts in the literature to model human thermoregulation
systems in order to predict central temperature and other heat stress indicators
(see [3, 9], among many others). These models depend on a wide range of variables,
including individual characteristics, surrounding textile and environmental factors. The
main objective of this work is to formulate a stable, realistic and versatile 2-D mathematical
model describing the heat transfer of the human foot (bare foot and foot surrounded
by textile materials). The novelty, but also the difficulty , lies on the theoretical multiphysics
that models the textile as a porous media, involving energy transport but also
mass transport of liquid water, water vapour and gas, including evaporation phenomena.
The numerical solution to the global problem involves a segregated algorithm and fixed
point techniques for the nonlinearities jointly with finite elements spatial discretizations.
Implementation has been performed through commercial software COMSOL TM Multiphysics.
