The human body: a complex thermal and controlled system.

Author(s) : DITTMAR A., DELHOMME G., SCHWENZFEIER L.

Summary

The human body is a thermal machine working in a "quasi" or almost insulating medium: the air. The thermal regulation is one of the latest main function appearing in the evolution of living beings. This function allows the optimum level of temperature, and the "minimal energy management" of the chemical reactions of the vital organs as brain, heart, liver... and also allows an activity which is independent of the external temperature, through a very complex regulation system. The thermal protection, clothing, the thermal modelling and simulation have to take into account these facts to be realistic, non "virtual" and really compatible with the human activity. The paper presents some basic notions in this field, as well as the mechanisms of some interactions between several main parameters.
