中文摘要 | 利用正交配置法解冪次非牛頓流體帶有點滯消散時之熱進口問題。冪次非牛頓流體在圓管中流動帶有點滯消散之現象時常在高分子加工上遇到。本文利用正交配置法來解在管壁定溫時之情況,由結果顯示,本方法可以適用於任意之Gz數,並且可以推廣至其他之幾何形狀之熱進口問題。 |
英文摘要 | Power law fluids flowing through a circular pipe with viscous dissipation are frequently treated in polymer processing. A numerical algorithm by orthogonal collocation has been developed to solve the constant wall temperature case. The results are found to be quite accurate for arbitary Graetz number and can be extended to any geometrical figures as long as the processes and boundary condition are prescribed. |
