| Outline of Final Research Achievements |
To properly predict thermal comfort using a thermal model of the human body, heat and moisture transfer in and around clothing must be evaluated. However, the low air velocity in clothing and the complex shape of the air layer complicates the modeling of ventilation in clothing. In this study, computational fluid dynamics (CFD) analysis around the human body considering the air layer in clothing was conducted to quantitatively grasp the air distribution in and around clothing by importing real shape data obtained by a laser scanner, for an adult human wearing single-layered clothing. The influence of the ventilation of clothing air layers on the heat flux at the skin surface under the clothing was determined to be minimal in typical indoor environmental conditions. In addition, application of a simpler model using ventilation calculation to this problem was tried based on the results of CFD analysis.
