Application of numerical simulation on performance evaluation of thermal protective clothing

Evaluating the performance of thermal protective clothing properly is significant for public safety．Following experiment research, numerical simulation has become an important means in related fields. From the aspects of development and validation of models, this paper reviews the current research status, such as heat transfer models, skin burn predictive models and fire simulation. The development process, characteristic and insufficient points of representative models are concluded. According to the development of related technologies, trends on numerical simulation on performance evaluation of thermal protective clothing are predicted. Full-scale simulation will be carried out based on the improvement of heat and moisture model. All-round evaluation of protective clothing will be realized combined with human thermal regulation model. Through the application on the optimization of thermal protective clothing, the practical value of numerical simulation can be expressed adequately.
