Thermodynamic modeling of micro heat engines for power generation
Thermodynamic modeling of micro heat engines for power generation
The need for compact, high power-density power sources has led to significant research interest in micro heat engines. However, there is a lack of suitable thermodynamic models which can be used to evaluate the power performance of micro heat engines by taking into consideration the effect of leakage and finite heat input. This work is the first to develop such a thermodynamic model to predict the upper limit of performance of micro heat engines. The model allows investigation of the effects of design parameters such as length and material properties on the theoretical output which can be used for design guidance. Results from this model are further illustrated by comparison to the reported P3 micro engine.

Abstract
The need for compact, high power-density power sources has led to significant research interest in micro heat engines. However, there is a lack of suitable thermodynamic models which can be used to evaluate the power performance of micro heat engines by taking into consideration the effect of leakage and finite heat input. This work is the first to develop such a thermodynamic model to predict the upper limit of performance of micro heat engines. The model allows investigation of the effects of design parameters such as length and material properties on the theoretical output which can be used for design guidance. Results from this model are further illustrated by comparison to the reported P3 micro engine.
