Résumé

In this paper, by simulating the influence of different air supply methods on the convective heat transfer of the human body, to explore the flow state and velocity of air boundary layer close to the surface of the human body, and then it is learned that the convection heat transfer is dominated by natural convection or forced convection in this kind of air supply mode. Through the simulation analysis of six kinds of air supply, we can get some conclusions. With the ventilation method of up-return down-supply and mechanical displacement ventilation, natural convection is the main way of convection heat transfer of the human body surface. Using side to send back and layer air supply, forced convection is the main way of convection heat transfer of the human body surface and the forced convection area is mainly found in the upper part of the human body surface. Adopt the ventilation mode of up-supply down-return and top to send back, forced convection is also the main way of convection heat transfer of the human body surface and the forced convection area is mainly found in the lower part of the human body surface.
