Abstract

The problem of modeling of the mechanism of a warmth transfer through sites which are located around a seam in clothes of a special purpose are considered and formalized. The mathematical dependence, reflecting temperature and heat flux density changes in an internal surface of the integrity of the sites which are located round a seam in protective clothes in the conditions of non-stationary heat conductivity is presented. The generalized model is received which allows to simulate, and consistently reproduce process of heating and to determine temperature and a heat flux density on an internal surface of the multilayered metallized material at any moment of time. Adequacy to the received mathematical model is confirmed experimentally.
