The paper presents verification and validation of an advanced numerical ,model, of ,heat, and moisture ,transfer, in the multi-layer ,protective clothing, and in components of the experimental stand subjected to either ,high, surroundings ,temperature, or ,high, radiative ,heat, flux emitted by hot objects. The developed ,model, included conductive-radiative ,heat transfer, in the hygroscopic porous fabrics and ...

Heat Transfer in Thin Fibrous Materials Under High Heat ...

A ,heat,-,transfer model, has been developed for two common, inherently flame-resistant fabrics, Nomex® IIIA and Kevlar®/PBI, when subjected to the ,high heat, fluxes used in bench top tests, such as the thermal ,protective, performance (TPP) test, ASTM D 4108. The apparent ,heat, capacity method was used to ,model, thermochemical reactions in these materials with information from thermal gravimetric ...
