Abstract
An analysis method that is not computationally demanding and can calculate the radiative heat transfer to each part of the human body is proposed. Following the estimation of the angle factors between the surrounding walls and the human body parts using the projected area factors in the previous paper, this paper describes a calculation procedure for the radiative heat fluxes to the body parts from the surrounding walls. In addition, it is shown that this numerical method can be extended to the estimation of the total radiative heat transfer to the targeted body parts, including the radiative heat fluxes from other body parts. Through a case study of a nonuniform radiative field in an indoor space, the effect of the proposed methodology, which includes the introduction of the projected area factors, consideration of obstacles, etc., on the evaluation results of the radiative heat flux to each part of the human body is discussed. Furthermore, an example evaluation of asymmetric radiative environments of an indoor space is carried out by arranging a number of human models with different postures, sizes, and directions on the floor. The results demonstrate that detailed discussions concerning radiative fields and thermal effects on human body parts anywhere in the room can be made by using the proposed analysis method.
