Abstract
In this paper, external radiation heat transfer coefficient and flux of a standing human body model are calculated for different emissivity coefficients
and various temperature differences. To do this, a standing human body sample is designed in such a way that hands and feet are totally open and
stretched. Soles are in contact with the ground and so do not have heat transfer. The results are extracted by weighted average method. Despite the
existence of the air around the body in reality, the convection heat transfer of human body with the surrounding air is neglected in order to prevent
errors and obtain more accurate results. The advantages of the suggested method are able to solve problems with different conditions and obtain more
accurate results without the limitations of laboratory experiments.
