Abstract

Human body acts as a heat engine and thermodynamically could be considered as an open system. The energy conversion and exergy analysis is obtained by applying the first and second laws of thermodynamic for this open system. The second law of thermodynamics introduces the useful concept of exergy. It enables the determination of the exergy consumption within the human body dependent on the human body parameters and environmental factors.

Energy generated by metabolism is an important factor on exergy efficiency and entropy generation of the body. Age is one of the parameters which has an effect on metabolism. In this paper, the thermal behavior of the human body is stimulated with two node models, and the human body parameters like age, mass, length, and weight are considered. The results indicate that the exergy efficiency increases until youth stage and after that it decreases during life span.
