Steady-State Simulations of the Human Thermal System,

Abstract

A mathematical model of the human thermal system under steady state conditions is formulated by using six cylindrical elements representing longitudinal segments of the head, torso, arms, and legs to approximate the human body. The model allows the use of different physiological parameters such as local rate of metabolic heat generation and local blood flow rate in various locations of an element. The regional variations of the physiological parameters are also taken into consideration. A set of ordinary differential equations representing the thermal behavior of all elements are approximated by a set of algebraic equations which resulted from the application of the explicit forward finite difference method. Specifically twenty-eight linear algebraic simultaneous equations are obtained by using five grid points in the spacial coordinate of each element. The model is then simulated for a number of steady state environmental conditions. (Author)
