| Abstract: | The method of selecting working liquid in thermoacoustic engines is presented. The calculations of thermodynamic and thermophysical properties of working liquid are described and studied. The numerical calculation of working liquid R218 is discussed. The calculated results are in good agreement with the experimental data available. The method of calculation and results are with satisfactory precision. The results obtained in this paper can be used for the research and development of thermoacoustic engines thermally driven by low grade heat source such as solar energy. |
