摘要

During the high-altitude operations, pilots would suffer from heat stress. The air ventilation clothing is usually utilized for promoting the comfort of the human-clothing microclimate. It is necessary to obtain accurate ventilation setting conditions and assess the cooling efficiency of clothing in such environments. A reasonable design of the pipeline layout and flow distribution of clothing could help improve the thermal comfort of the human body. In this study, A three-dimensional human body model with the air ventilation clothing was established, and the simulation of body temperature distribution was conducted with ANSYS FLUENT software. The temperature distribution on the surface of human body skin and the outer surface of clothing were compared when the ventilation temperature is 18 ℃. In general, the distribution range of skin temperature was from 31 to 37 ℃. Overall, the results of human body and clothing temperatures calculated were relatively uniform. In accordance with the calculation results, the wind temperature and flow rate which could maintain thermal comfort of the human body were suggested.
