In order to study the interaction between the human body, clothing and environment in a low-temperature environment, a three-dimensional human thermoregulation model was established based on real human body scanning images.The human body is divided into 12 parts by dividing the body into core, equivalent, skin and clothing layers.Further CFD numerical simulation was carried out to realize the measurement and calculation of human physiological parameters, such as human skin temperature, core temperature, and average temperature of the garment surface, in a low-temperature environment. Explored the clothing surface heat transfer, clothing surface average temperature, as well as human skin surface heat transfer, local skin temperature change rule with the external environmental temperature, for the study of the human body in the low-temperature environment of heat transfer characteristics to establish the basis. In order to verify the accuracy of the developed numerical model of the human body, the simulated values of the human body model were compared with the experimental measurements of the human local skin temperature and the simulated values in the literature. The results show that the maximum relative error between the local skin temperature of the human numerical model and the experimental measurements of the human body is 3.43%, and the human numerical model has a high degree of accuracy.
