Modeling Male Temperature Profiles with the Finite Element Method and Anatomically Correct Human Torsos
Abstract
This paper demonstrates a novel approach in human thermoregulatory modeling. A male torso model was created from medical image data. This allowed for accurate geometry of the organs to be used when modeling thermoregulation. Thermoregulation was simulated through heat transfer using finite element analysis. The thermoregulatory activities consisted of vasodilation, vasoconstriction, sweating, and shivering. They all work together to attempt to create heat balance within the body. The simulations show that temperature profiles and thermoregulatory responses can be predicted based on given the environmental conditions. In warm ambient temperatures, sweating and vasodilation occur in an attempt to exacerbate heat loss, while in cold ambient temperatures, shivering occurs to generate more heat and vasoconstriction occurs to lessen heat loss. The paths of the rectal and heart/esophageal temperatures compared well with similar temperatures recorded during previous studies, but the temperatures sometimes deviate significantly.
