Design, Development and Testing of a Stirling Engine

Abstract

This paper concerned with the design, development and testing of a gamma Stirling engine. The experimental apparatuses were also developed to determine the engine performance at varying speeds and hot-side temperatures. The measurements were then compared with the calculated power. In the experiment, an electric heater was used as the heat source, and the rope-brake method was used to measure engine torque. From the experiment, the lowest different temperature of the engine that could start the engine was 63.8 °C, the engine maximum speed was 81.0 rpm, and the maximum output power of the engine was 0.022 W at the working temperature of 148 °C and speed of 54.0 rpm. The maximum overall efficiency of the apparatus was 0.0646% at the same conditions.
