초록

This paper compares the output power of different types of small Stirling engines in conjunction with the utilization of low grade thermal energy. A series of experimental measurements were performed to assess the output power of each engine under different conditions of the temperature difference between the hot and cold ends as well as applied weight. Results are presented in terms of torque and output power per heat transfer area. Among tested, the MM-7 engine produced the highest power of 4.455mW ($321mW/m^2$) under a temperature difference of $40^{\circ}C$.
