- Abstract
High-temperature operation protective clothing should have good thermal protection and availability. Under the condition of reducing the research and development cost, the thickness of the protective clothing for high-temperature operation is optimized. Firstly, the three-dimensional heat conduction process is reduced to one-dimensional problem. Based on Fourier′s law of thermal conductance, steady-state heat conduction equations and heat transfer principles, a one-dimensional steady-state heat conduction model is established, and the relationship of thickness, time, and temperature difference is obtained. The finite difference method is used to solve the temperature distribution. The error analysis results verify the reliability of the model. Under the condition that the constraint conditions are satisfied, the optimal design of the second and fourth layer thickness of the protective clothing is conducted by using Monte Carlo algorithm, which can avoid falling into the local optimal solution, reduce the research and development cost, and shorten the research and development cycle. At the same time, it can provide a basis for the design of related high-temperature thermal protective clothing and the development of its derivative industry.
