Comparison of skin surface temperatures between subjective experiments and numerical predictions by using a modified 65 MN Thermoregulation model under solar radiation

A modified 65MN(Multi-Nodes) thermoregulation model is tested for the evaluation of the skin surfacetemperature distributions in each body part under solar radiation. The present model can be also applicable for the coupled analysis of CFD and radiation. Skin surface temperatures predicted by this model are compared with those by subjective experiments in the real scale experimental atrium under solar radiation. Predicted each skin surface temperature almost corresponds to that of subjective experiment with the accuracy around 1 degree Celsius difference. However, the prediction accuracy on the legs and arms is poor by comparison with that on other body parts, which must be required the improvement of prediction accuracy on the legs and arms. As a whole, the present model is a useful tool for the prediction of skin surface temperature distribution under solar radiation.
