| Models of human thermoregulation and heat transfer date have been developed for a wide range of applications. Many existing models are of limited usefulness in asymmetric thermal environments, such as may be encountered during an EVA. A further limitation is that models based on a standard man model are not readily scalable to represent large or small subjects.;This work describes development of a new human thermal model derived from the 41-node Man Model and Fiala Model. Each segment consists of geometrical shapes made up of layers of the appropriate tissue types. These segments are connected only by the flow of blood from a central blood pool to each part.;Scaling rules are developed to enable simulation of small and large subjects. Results show the model simulates core and surface temperature histories, sweat evaporation and metabolic rates which generally are consistent with controlled exposures of human subjects. |
