Abstract
The temperature distribution and thickness design of high temperature protective clothing are studied in this paper. Based on the data provided by China mathematical modeling competition in 2018. We establish the temperature distribution model and skin layer heat conduction and burn model. The interface continuous conditional difference method, differential iterative method, least squares method and the chasing method are used to solve the given temperature distribution on the protective clothing in the environment, and analyze protective clothing meeting the actual needs.
Highlights
When working in a high temperature environment, workers often need to wear adiabatic protective clothing, which can effectively prevent heatstroke, burns and other injuries, often have the characteristics of flame retardancy, liquid repellency, etc
Lu studied the performance of protective clothing against liquid splash and its permeability and heat and moisture conductivity in high temperature environment, and used skin burn prediction model to predict the protection of thermal protective clothing [1]
Tian et al applied numerical simulation to evaluate the performance of high temperature protective clothing, and summarized the characteristics and disadvantages of typical heat conduction model and skin burn model [2]
Summary
When working in a high temperature environment, workers often need to wear adiabatic protective clothing, which can effectively prevent heatstroke, burns and other injuries, often have the characteristics of flame retardancy, liquid repellency, etc. Lu studied the performance of protective clothing against liquid splash and its permeability and heat and moisture conductivity in high temperature environment, and used skin burn prediction model to predict the protection of thermal protective clothing [1]. For the application of phase change materials, Zhu and others conducted more in-depth research, analyzing from the aspects of reducing thermal stress, improving the comfort of protective clothing, preventing sudden changes in temperature, etc. Lu Linzhen carried out related research and established the heat transfer model of the protective clothing-air layer-skin system, and the influence of some parameters on the protective performance [13]. This paper optimizes the thickness of the garment in a specific environment to achieve the best protection
