中文摘要 | 本文說明水平及垂直加熱平板混合對流之參數分析,在水平板上自然對流由不勻 之溫度或密度引起並加在強制對流上,在加熱垂直板由往上或往下之強制流加在自然對流上 。不需經由數值計算或實驗數據參數分析可以推導混合對流相關函數式。本文也說明特徵速 度,邊界層厚度及紐塞數之關係。本文結果與現有之相關函數作比較。 |
英文摘要 | Parametric analysis for mixed convection flows on heated horizontal and vertical plates is presented. For the case of horizontal plate, natural convection flow induced by an uneven temperature or density distribution is superimposed on the forced flow on the heated horizontal surface. For the case of vertical plate, a forced flow is posed on the natural convection flow along the heated vertical surface in the ascending or the descending direction. Parametric analysis is made for the mixed convection flows to derive correlation equatinons without deduction from the results of numerical computation or experimental data. Relationships for the characteristic velocity, the boundary layer thickness, and the Nusselt number are presented. Comparisons with the existing correlations are made. |
