| Research Abstract |
In this research, we developed a new model of evaluating the thermal comfort "Computational Thermal Manikin" by CFD.This year the follows have been conducted.
(1) Measurement by using an experimental thermal manikin
Temperature and flow fields around a human body have been conducted by using a Low-Re Number K-epsilon model. To evaluate the precision of the numerical calculation, measurement of the temperature and velocity boundary layr is being done on an experimental thermal manikin. Thus, the convective heat transfer characteristics around the human body will be mastered.
(2) Coupled Convection and Radiation Simulation of the Computational thermal manikin
To clarify the sensible heat transfer characteristics between the human body and his environment,
coupled convective and radiant simulation is being conducted. From the complicated shape of the human body, the view factor is calculated by Monte Method. Gebhart absorption coefficient is used. The air flow simulation is based on Low-Re Number k-epsilon model.
(3) Inclusion the breathing and modelling of the latent heat transfer
The breathing must be including in the air simulation. Moisture transfer is also considered by using the concept of wettednes on treatment of the sweat on the skin surface of the human body. Thus the total heat transfer between the human body and the environment can be decided by using these coupled simulations.
