Abstract

diative and conduction heat transfers are considered within the clothing with a focus on the first skin layer. The protective clothing is
modelled as a 1D solid medium, featuring three layers of tissues, separated by several air-gaps. A parametric analysis is performed in the aim to predict the effect of conductive and radiative tissue properties fluctuation on the first skin's layer temperature.The obtained results using the finite element software COMSOL Multiphysicsare compared with stationary 2-D calculations, and faced to unsteady simulations based on the finite volume method. A relative reduction of 50% in the absorptivity of the e skin, (in the case of wearing a fine knitted fabric).
makes it possible to reduce the temperature of the first skin’s layer to a tolerable value.
