This paper seeks to predict the heat transfer properties of the numerical manikin. It also aims to establish a simplified clothing model based on computational fluid dynamics (CFD) to predict the temperature in air layers between thermal manikin and clothing under different environments. The field experiments of nude or clothed thermal manikin were conducted in a climatic chamber. The CFD method was employed to build a nude or clothed numerical manikin to simulate the field experiment. The distribution of temperature and the velocity field around the nude human body and heat transfer coefficients were simulated in the optimized numerical climate chamber with a temperature of 20oC and velocity of 0.05m/s. The temperature in air layers entrapped in clothing dressed on the torso of manikin was also predicted under the same environmental condition. The CFD results showed good agreement with that of the nude or the dressed thermal manikin experiment. It demonstrated that CFD could properly predict the heat transfer properties of indoor human and temperature distribution in the air layer between human body and clothing.

Keywords:Thermal manikin; CFD simulation; Air layer; Heat transfer
