Abstract: Considering that human body shape affects directly the thermal and moisture transfer process‚we constructed and meshed a realistic geometric figure of human body from the scanned data of a real person.Gagge2-node model is used to describe the thermoregulation of human body‚where each surface of the finite volume cells of the skin is interfaced with external environment.Through simulation‚we generated the3D dynamic temperature distribution and moisture distribution on the skin surface and in the environment‚The results are used to improve the3D garments design.
