Abstract—Based on the finite element method a transient 3- D clothed human thermoregulation model is developed. Geometry information of human body is obtained by 3-D scanning data. The controlled system of human body includes three sub-systems which are the tissue system, the circulatory system, and the respiratory system. The 6-node wedge and 8-node block isoparametric elements are used to simulate the human body tissues. The mechanisms of coupled heat and moisture transfer in clothing are considered. Then, the human model is interfaced with the clothing model by using the boundary conditions, and the equations of the models are solved by finite element method. Finally, the nude and clothed human body model predictions are compared with the published experimental data at a variety of ambient conditions, and a series of 3-D figures to show the prediction results of the temperature and water vapor concentration distributions is given.
