Abstract

Stirling Engines have a wide range of practical uses, including propulsion and refrigeration. The Stirling cycle heat motor has a decent potential for use in the future given certain benefits like external combustion, fuel adaptability and flexibility.  Stirling engines are used extensively in the cryogenic and submarines field, but prime mover applications are still underdeveloped. The main purpose of this study is to develop accurate thermodynamic numerical models that can predict performance and provide a means of further optimization. Therefore, this paper shows numerical modelling simulation, validation, and parametric optimization of a Single-Cylinder Rhombic Drive Beta-Configuration Stirling Engine filled with CuO-ZnO as a working fluid. A general 1st Order-Dimensional numerical model is adapted throughout the prediction of Stirling engine performance. The numerical model is determined based on swept and un-swept volume, overall geometrical parameters, and operating fluid properties The cycle pressure, volumetric displacement, work, and energy produced during the expansion and compression cycles in the cylinder are predicted using Schmidt and Ideal Adiabatic analysis based on Berchowitz and Urieli's technique. At a speed of 300 rpm, the engine produces 946.54 W of power in the designated working condition. Based on a 90° phase angle setting, 4.5 bar of Copper Oxide-Zinc Oxide (CuO-ZnO) cylinder charge pressure, 1073 K of expansion space temperature, and 294 K of cooler space temperature, the stated thermal efficiency is 73 percent.
