摘要
人们在高温条件下工作时,需要穿专用服装避免灼伤。文章首先利用斯蒂芬—波尔兹曼模型以及织物的密度、比热容等参数得到4层材料在不同时刻的温度分布;其次,采用基于热湿耦合传递的模型列出偏微分方程,得到了第二层的厚度;最后,在此基础上,利用最小二乘法最终求解出防热服第二、四层的最优厚度。
When work in high temperature,people need to wear special clothes to avoid burns.This paper first uses Stephen-Boltzmann model,fabric density and specific heat capacity to obtain the temperature distribution of four layers of materials at different times.Then uses the model based on coupled thermal and humidity transfer to list the partial differential equation,and get the thickness of the second layer.Finally,on this basis,the optimal thickness of the second and the fourth layers of heat-proof clothing can be obtained by the least square method.
