Convective Heat Transfer Coefficient at Each Part of Human Body Exposed to Steady Airflow

Abstract

In order to understand the convective heat transfer from each part of the human body surface when exposed to a steady air flow, experiments were conducted using a thermal manikin (TM), heat flux sensors, and radiant heat flux sensors. The experimental results for the convective heat transfer coefficient(CHTC) were compared with the experimental formulas of the previous research and the results of CFD analysis. The CHTC for the whole body of TM was close to the experimental formula of the previous research, and there was no significant difference from the CFD analysis. For each part of TM, the local CHTC calculated from the heat flux measured by the heat flow sensor was compared to the averaged CHTC of each body part calculated from the heat generation value of TM.
