Abstract

This research studied the thermal performance of the solar-Stirling engine using solar radiation as heat source, by developing thermal models of the Stirling engine, and studied the thermal performance of the system by measuring various parameters, i.e. the rate of change in water temperature (dTw) flowing through the heat receiver, absorbed heat value of the calorimeter (Qw), and stagnation temperature (Tps) of the heat receiver. Parabolic dishes are positioned to achieve solar radiation. The heat is focused to the focal point, which places a copper calorimeter as a thermal receiver to find out the absorbed heat input, and then change the heat receiver into a Stirling engine. The engine performance test was carried out, the study indicated that the absorbed energy using copper calorimeter was 178.62 W, heat loss was 2.524 W at a solar radiation intensity of 943 W/m2. The parabolic dish has a thermal efficiency of 47.11 %. The engine's thermal input was 0.982 W, with a heat loss of 0.840 W at a solar radiation of 962.9 W/m2. The temperature difference increases the speed and the thermal performance of the engine. The Stirling engine-Parabolic dish has a thermal efficiency of 0.036 %.
