Thermal Protective Clothing for High Temperature Environment

The research on thermal protective clothing aims to reveal the heat transfer law inside the thermal protective fabric, and provide scientific reference for the research and development of thermal protective clothing, which is of great significance for reducing the skin damage of workers in high temperature environment. In this paper, the heat transfer model of "thermal protective clothing-air layer-skin" system is established according to the thermal conduction mechanism of heat. The finite difference method is used to classify the heat conduction partial differential equations by time and space, discretize them into classical implicit format, and then iterate. The method obtains the numerical solution of the equation and obtains the obtained temperature distribution in the form of a matrix and a three-dimensional image.
