Simulation Study Of The Human Dress Dynamic Heat And Moisture Comfort

This paper summarizes the scientific contents and phytogeny on the heat and moisture comfort in clothing. On the based of the former researches about simulation of the heat and moisture comfort of human beings, analyzed each physic phenomenon and effective factor in the course of the heat and moisture transfer.The key contents of this paper are discussed mainly. That' s, the dynamic simulation analysis of heat and moisture comfort in body wearing.First, we found mathematical model according to the concept of characteristic unit of volume, the continual media approach and the basic laws about heat, mass and momentum transfer, also, many phenomenon are taken into account, such as the heat conduction, convection, radiation, diffuse and phase transformation, heat and moisture's coupling effect and so on. At the same time, some important parameters in the model are analyzed.Then, we take finite difference method to discretely analyze the mathematical model and list equations of griddling points,.More, we design the compute program using Matlab language to simulate the temperature field and wet concentration field. As a result, we get perfect 3D dynamic model, and by using it, we can find the laws of the heat and moisture transfer and the laws about the change following time of correlative parameters, also ,we can simulate the heat and moisture transfer in the dynamic course of different activities of human.Last, we get the temperature and wet concentration data; those results are consistent with the experimental data that reported in other literatures, which validates the model . Obviously, the dynamic 3D simulation of the heat and moisture comfort of human beings is realistic.
