中文摘要 | 本文研究分析有關非牛頓冪次律(Power-Law)流體在噴流(Submerged Jets)層流流場之速度及溫度場的效應。經由比較不同的冪次律流體在噴流流場中速度及溫度場分佈的差異,以了解不同的冪次律流體在流場中的影響。應用全相似轉換觀點,選擇適當參數將動量方程式轉換成非線性微分方程式;並應用局部相似轉換觀點,將能量方程式轉換成非線性微分方程式求解。數值計算方面,應用四階Runge-Kutta積分法之型式組合數值求解方法中之射值法(Shooting Method)計算出速度及溫度之分佈。並且利用迴歸分析,得到N.=f(Pr, n, Re)的關係式。 |
英文摘要 | The flow fluid and temperature distribution of the non-Newtonian power-law fluid in a laminar submerged 2-D jet were analyzed in the present study. The effects to the flow of the power-law fluid were examined by comparing the velocity and temperature profiles of different power. The shooting method with forth-order Runge-Kutta integration was performed to compute numerically the velocity and temperature profiles. Also the empirical form Nu=f (Pr,n,Re) was obtained by the regression analysis. |
