中文摘要 | 本文以函數指定法求解逆向熱傳導問題,方法中採用最小平方法並引用未來溫度 的觀念以連續估測的方式來預測物體表面的熱通量與溫度,此方法有原理簡單與計算效率高 等觀點。本文除了以理論探討逆向熱傳導問題,文中並透過實驗來驗證理論之可行性。為了 實驗的完整性,本文採用兩種不同的試件 (半無限長物體與薄板一端絕熱 ),並配合六種不 同的表面熱通量曲線 (方波、弦波、三角波、鋸齒波、脈衝與常數 ) 來做實驗。 實驗結果 顯示本方法能藉由物體內部一點之溫度量測資料正確估測出表面的未知邊界條件。 |
英文摘要 | The function specification method is adopted to solve the inverse heat conduction problem in this paper. In this method, the surface heat flux and temperature are estimated sequentially by the least-squares method that empolys the concept of future temperatures. The method is simple in concept and computationally efficient. In addition to theoretical study of the inverse heat conduction problem, the theory is confirmed by experiment. Two samples (a semi-infinite body and a thin plate insulated at one side) and six surface heat fluxes (square, sin, triangular, saw, impulse and constant waves) are used for completeness of the experiment. The experimental results show that the unknown boundary conditions can be estimated accurately by the method from the temperature measurements at one interior point. |
