A human being’s limb can be modeled in terms of three physiological layers from inside to outside in the radial direction: the bone, the muscle and the skin as shown in Fig. 1. The skin layer could be regarded as a kind of porous tissue at macro-scale, though it is not a perfect porous material. This is because the skin layer has all the important physical characteristics of a porous medium: the solid matrix, skin tissue covering all the objective space; and the voids/pores formed by sweat glands that are interconnected. This allows one to use the model for an unsaturated porous medium to describe the flow and heat transfer of sweat in the skin layer.
