中文摘要 | 本文係利用馮卡門面(Von Ka'rma'm)積分動量方程式求解斜壁冪律亂流之邊界層 厚度及薄膜厚度,並對其成長、重合與衰退加以研討,再以數學近似法求出薄膜性冪律亂流 延斜壁流動時各種流體參數之關係。所得結果證實與特例流層 (β =0.25) 時之結果相吻合 。 |
英文摘要 | The research is using Von Ka'rma'm integral momentum equation to study the turbulent boundary layer of power law thin film flow along an inclined wall. The thicknesses of the boundary layer and the film, including their growth, onset point and decay, are investigated in detail. In this study, mathematical approximation method is applied to obtain the relationships of various fluid parameters. The results are in corresponding with the experimental runs. |
