Optimization analysis of high temperature workwear based on one-dimensional multilayer flat wall heat transfer process

In order to design costumes that can satisfy high temperature working environment, this paper constructed a one-dimensional heat conduction model through Fourier law and finite difference method. As the actual situation is one-dimensional unsteady heat conduction, numerical analysis method and MATLAB programming are required to solve the problem. The accuracy of the model is confirmed by error analysis. Finally, the sensitivity of the model is estimated roughly. Correlation analysis is made on the measurement of heat release and the convergence rate of temperature field in the working process of high temperature working clothes, and the prospect of high temperature resistant clothing is predicted.
