Modeling Heat Transfer in Phase Change Material Bedded Firefighting Protective Clothing under Fire Exposure

摘要：

In this paper, a mathematical model of heat transport in phase change material (PCM) bedded firefighting protective clothing under actual fire exposure is presented. The sweat evaporation rate as a function of temperature is considered by droplet vaporization model. The phase change process of PCM is represented by the erfc smooth function. The distribution of temperature versus time at different location in the fabric-airgap-skin system is determined. The maximum duration for getting second degree burn injury under the protection of firefighting clothing with or without PCM layer and the critical melting temperature of PCM is predicted. The computation results show that the addition of an appropriate PCM into firefighting protective clothing could improve the thermal performance of garment.
