Energy transfer in protective clothing and in superficial skin tissue was math. and numerically modeled assuming assuming heat conduction and non-gray thermal radiation in the porous textile layers and air gaps accompanied by water vapor diffusion in pores and air spaces as well as sorption and desorption of liq. water from fabric fibers. Non-equil. heat transfer between the tissue and arterial blood as well as variable blood perfusion rate were simulated in the skin and muscle applying two-equation bioheat transfer model. The results were used to access influence of the heat flux changes and exposition time on degree of skin burns and protective performance of garments.
