Popis:	This paper outlines experimental and theoretical work on heat transfer through cold-weather clothing systems consisting of a somewhat permeable sheath over a layer of insulation batting. The experiments were carried out in a wind tunnel with the clothing systems installed on a 0.165 m diameter heated circular cylinder. Measurements included pressure distributions, temperatures and heat fluxes at several wind speeds. It was found possible to correlate the experimental results in terms of a single parameter, giving a compact presentation suitable for design guidance. A simple theoretical model is outlined. Predicted maximum heat fluxes agree well with the experimental data although the shapes of the predicted and experimental heat flux distributions around the cylinder differ substantially.
