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。 本研究對冪次律流體噴流流場的分析,主要採數值的模擬分析方式。本體是應用Patankar[13]所發展的控制體積結合SIMPLER的數值流程加以計算,相關的數值分析方法有高斯一賽德法(Gauss-Seidel)配合緩鬆弛法(under-relation)在對流項則應用冪次律法則(power-law scheme)處理。 |
英文摘要 | The fluid flow and temperature distribution of the non-Newtonian power-law fluid in a laminer submerged 2-D jet were analyzed in the present study. The effects of the power-law fluid were examined by comparing the velocity and temperature profiles of different powers. The simulation analysis process has been developed and performed by using Patankar's control volume method. The convective term is modified by the power law scheme. The Gauss-Seidel algorithm with the under-relaxation method is implemented to the SIMPLER algorithm to obtain the solutions. |
