In this paper, the authors measure the convective heat transfer coefficient of a human body in outdoor environment by means of wind tunnel test and CFD (Computational Fluid Dynamics) analysis. The accuracy of CFD analysis was verified by comparing both results. As a result, enough accuracy of CFD analysis was confirmed. Therefore, the authors implement the sensitivity analysis based on CFD analysis for a mean convective heat transfer coefficient of a human body when velocity and turbulence intensity of the wind were changed. At last, the authors develop the formula for a mean convective heat transfer coefficient of a human body in outdoor environment. This formula can evaluate both influences of velocity and turbulence intensity of the wind on the mean convective heat transfer coefficient of a human body. The development of this formula has a great meaning to comprehend characteristics of a heat release in outdoor environment.
