Abstract: Accurate establishment  scientific heat transfer model for thermal protective clothing can reduce the costs and shorten the cycle of research and development. Therefore, a preliminary temperature distribution model is established based on  heat conduction principles, and Fourier's law and is modified by retardation factors  with controlling parameters. Monte Carlo algorithm is then applied to obtain the relevant parameters in the temperature distribution model according to the experimental data.Finally, an excellent heat transfer model of protective clothing is obtained.

Key words: Monte Carlo algorithm, heat conduction, protective clothing, heat transfer model
