Abstract:

In order to improve the accuracy of the evaluation of thermal protective performance of firefighter protective clothing exposure to low level radiation, existing experimental evaluation methods and numerical modeling methods of heat transfer were analyzed. Based on the research of heat transfer mechanism in firefighter protective clothing, the research status of heat and moisture transfer models was reviewed. The factors which affected the thermal protective performance were summarized. The evaluation methods of the thermal protective performance of firefighter clothing in low level radiation were summarized, and the effect of experiment methods and experimental equipment on the prediction of thermal protective performance were analyzed from two aspects of differences and limitations of test methods. The application of numerical simulation in the heat and moisture transfer was summarized. Simulating the exposure conditions in low level radiation exactly should be proposed in the future study to improving the accuracy of the evaluation of thermal protective performance in firefight clothing.

Key words: low level radiation, firefighter protective clothing, heat transfer mechanism, performance evaluation
