本文以不同的操作參數與設計參數,針對系統質量、系統溫度、系統壓力、功、氣體的熱對流係數、系統熱傳量、系統的洩漏量、壓縮機效率、三角轉子在轉動過程中所承受的合力與外界供給三角轉子的扭力變化等10種變化因子進行探討與比較,其中操作條件為壓縮機轉速與進、排氣埠面積,設計參數為各系統之間的間隙量。模擬結果顯示,壓縮機轉速對於系統質量、系統溫度、系統壓力、功、氣體的熱對流係數與系統熱傳量影響較大;間隙量則是對系統的洩漏量、壓縮機效率、三角轉子所承受的合力與三角轉子所承受的扭力影響較大,其中當間隙量為0.5e-6 (m)時,效率為91.32 %,間隙量為2.5e-5 (m)時,效率為55.21 %,進、排氣埠面積對於本文所設定的探討因子則是完全沒影響。

The equations for the envelopes of the housing and the triangular rotor of a Wankel compressor have been developed in this study, and thermodynamic model used to analyze the performance of the compressor has been developed to analyze the performance of the compressor.
In order to minimize leakage between inlet and outlet port, the triangular rotor is required to contact the middle apex of the housing all the time. However, it would cause interference in the period of rotation. A modification procedure has been developed in this paper to overcome the problem of interference. The variations of chamber volume and contact area between rotor and housing were obtained with equations of the housing envelope and rotor.
In order to compare the variations of mass, pressure, temperature, work, heat convection coefficient, heat convection, mass loss, efficiency of the Wankel compressor, the equilibrium force and moment of triangular rotor in single zone by five values of speed, leakage and intake/exhaust port area, the results of calculation showed that, the influence of speed on mass, pressure, temperature, work, heat convection coefficient and heat convection are very important; The efficiency of the Wankel compressor, mass loss and the equilibrium force and moment of triangular rotor depend on the leakage value. When leakage value is 0.5e-6 (m), the efficiency is 91.32 percent; as leakage value increase to 2.5e-5 (m), the efficiency reduces significantly to 55.21 percent.
