Abstract
A numerical model coupling the three-dimensional field and human thermoregulatory models is proposed and developed. A high-Re k-epsilon turbulence model is used for the field simulation. A modified 25-node model of human thermoregulation is adopted to predict human thermal response in physiological parameters, such as body temperature and body heat loss. Distributions of air velocity, temperature, and moisture content are demonstrated in a crowded enclosure with mechanical ventilation under two ventilation rates. The results are analyzed and discussed. The coupling model is useful in assisting and verifying ventilation and air-conditioning system designs.
