During a flash fire exposure, this intelligent garment will absorb a significant amount of the incident heat flux due to evaporation of the injected water, thus limiting the temperature increase and the total heat flux to the firefighter's skin. A comprehensive mathematical model of heat and mass transport in the fabric layer during the flash fire exposure is suggested and numerically implemented using a finite-volume technique. A computational investigation is performed to optimize the performance of this novel garment system in terms of the activation temperature and the necessary amount of injected water.}, number={5}, journal={NUMERICAL HEAT TRANSFER PART A-APPLICATIONS}, author={Chitrphiromsri, P and Kuznetsov, AV and Song, G and Barker, RL}, year={2006}, month={Sep}, pages={427–450} } @article{chitrphiromsri_kuznetsov_2005, title={Porous medium model for investigating transient heat and moisture transport in firefighter protective clothing under high-intensity thermal exposure}, volume={8}, DOI={10.1615/jpormedia.v8.i5.80}, abstractNote={The aim of this study is to understand the performance of firefighter protective clothing in preventing thermal injury of skin that may result from exposure to high-intensity thermal radiation. A mathematical model is developed to study transient heat and moisture transport through multilayer fabric assemblies. The model accounts for changes in thermophysical and transport properties of the fabric due to the presence of moisture. Numerical simulations are performed to study heat and moisture transport in wet fabrics that are subjected to intensive flash fire exposure. The numerical solutions are further analyzed to provide a detailed physical understanding of the transport processes. Moisture in the fabric tends to vaporize starting from the outside surface of the fabric to the inside surface of the fabric during heating, and then part of it recondenses in the interior of the fabric during the cooldown. It is observed that the temperature distribution in the fabric layers and the total heat flux to the skin are significantly influenced by the amount and distribution of the moisture in the protective clothing.}, number={5}, journal={Journal of Porous Media}, author={Chitrphiromsri, P. and Kuznetsov, A.

This model incorporates characteristics of the simulated flash fire generated in the chamber and the heat-induced changes in fabric thermophysical properties. The model also accounts for clothing air layers between the garment and the manikin. The model is validated using an instrumented manikin fire test system. Results from the numerical model help contribute to a better understanding of the heat transfer process in protective garments exposed to intense flash fires, and to establishing systematic methods for engineering materials and garments to produce optimum thermal protective performance. }, number={12}, journal={TEXTILE RESEARCH JOURNAL}, author={Song, GW and Barker, RL and Hamouda, H and Kuznetsov, AV and Chitrphiromsri, P and Grimes, RV}, year={2004}, month={Dec}, pages={1033–1040} }
