Abstract
In order to clarify the influence of air flow between skin and clothing by natural convection on heat and moisture transfer around human body, the air distribution around human body is analyzed by using CFD for a simplified model of human body and clothing. By inputting the air flow rate through the air layer and convective heat transfer coefficients from skin to air layer and from clothing to air layer obtained by CFD analysis, the heat and moisture behavior around human body is analyzed by the model of human thermal system combined with simultaneous heat and moisture transfer model for clothing. The influence of thc air flow through the air layer between skin and clothing is not significant when the thickness of air layer is less than 0.5 cm. When the thickness of the air layer is 1 cm, the influence of the air flow on heat and moisture transfer should be properly taken into account.
