Abstract :
This paper presents a simplified yet comprehensive mathematical model to predict steady state temperature distribution for various regions of male clothed human operators who are healthy, passive/active and lean/obese under the influence of different environmental conditions using thermoregulatory control concept, The present mode] is able to predict the core temperature, (7. ) close to 37 C for a healthy, passive/active and leari/obese operator at normal ambient temperatures. It is observed that due to increase in body fat, BF the skin temperature, (Ts ) of the operator decreases by a small amount. However, the effect of age of the operator on Tf is found to be insignificant. The present model has been validated against the experimental data available in the literature.
