Prototype calculations of a free displacer stirling engine designed for the use of solar energy in irrigation and electricity production

In this study, made on the use of solar energy for irrigation and electricity production, initially the statistical data of solar energy density of Türkiye was examined and found to be adequate. In order to use the solar energy in irrigation and electricity production, the development of an externally heated, structurally simple, small and light engine is required. In the study, after examination of the literature of Stirling engines, an engine model has been designed that uses air as the working fluid and works with Otto cycle by means of a free displacer. The thermal and dynamic analyses of the model was carrieâ out and the dimensions of a prototype with 500 Watt power output were estimated.
