    Abstract: 本研究主要是探討芝麻焙炒爐的設計因子,利用因次分析將焙炒爐在X 域下的變數配成無因次群,由無因次群畫出無因次圖後,以內差法在π 域做出無因次曲面,以無因次曲面預測各種情況下的爐床出口溫度,經由數值模擬軟體印證後,模擬值與內差值的相對誤差小於1. 95% 。經由Pentium Ⅱ 266 電腦運算,內差結果所需時間小於l 秒,相反地模擬所得的結果卻需要約90 分鐘的時間,所以因次分析與內差法相結合的確能預測其它變數值組合下的出口溫度,進而縮短焙炒爐設計的時間。
    The main work of this research is to study the factors of designing a rotary kiln. Using the dimensional analysis, the kiln design variables in X space are transformed into the dimensionless groups. After plotting the dimensionless diagram, we can apply the interpolation method to generate the dimensionless curve in .pi. space. The SimLAB 2000 Simulator and the package MATLAB prove that the maximum relative errors between the simulation and interpolation results are less than 1.95%. By using the Pentium II 266 PC, the interpolation method costs less than one second; however, for the SimLAB 2000 Simulator, it costs about 90 minutes to compute the results. Therefore, the dimensional analysis and interpolation method can speed up the rotary kiln design work.
