Abstract. The paper presents study of coupled aerodynamic and thermodynamic interaction between human body and environment under low temperature and wind conditions. The passive heating or the prescribed heat flux model is used to model the metabolic heat release by human body. The heat flux is selected from the condition that the surface temperatures take experimental values for certain environmental conditions. Heat transport inside of the clothes, radiation, natural and forced convection are simulated using OpenFOAM toolkit. Results are obtained for the schematic human body in form of a cylinder and real body. It was shown that only forced convection and heat conduction play an essential role at wind conditions and low temperatures whereas the radiation and natural convection can be neglected. To keep the human body temperature on the acceptable level, the local heating elements can be embedded into the clothes textile. The power of this heating was calculated using the models of aero-thermodynamic coupled interaction including heat radiation. Under strong wind conditions the heat transfer from the human body can sufficiently be increased due to change of the thermal conductivity caused by cloth deformation under wind induced pressures. The results of the work are used for the design of real protection clothes for the work under low temperatures and wind conditions in oil gas industry. 7703
