碩士 === 國立成功大學 === 航空太空工程學系 === 102 === This thesis is intended for investigation of theoretical model of the pulse-tube Stirling engine. The model includes dynamic and thermodynamic modules. The properties of dynamic and thermodynamic in each chamber of the engine are predicted. The pressure drop and heat transfer are also considered. The parametric analysis results show that the geometric parameters of the engine have optimal design values, such as the length and diameter of connect tube, the number of fin in the heater. In this study, thermodynamic module is incorporated with simplified conjugate gradient method (SCGM) to optimize three geometric parameters. According to the prediction result after optimization, the power output could increase from 22.76W to 32.56W under 1-atm, 1000C at 1000 rpm of rotation speed, and the performance improvement is 43.06%.
