中文摘要 | 本文係研究圓柱形發熱體置於密閉空間內自然對流熱傳遞情形。分別採用全像干 涉術實驗及數值模擬方法, 以量測或計算出空間內溫度場和流場的變化。 所探討的參數有 Ra 數及熱源所處位置對整個區間溫度場和流場之影響,最後並比較實驗和數值結果。 |
英文摘要 | Experimental holographic interferometry and numerical simulation are presented to study the natural convection heat transfer over a cylinder heated within an enclosed rectangular space. The measurement and calculation of temperature and velocity flow fields in the space are obtained. Two parameters--the Rayleigh number and the location of heated cylinder are considered. Moreover, the comparisons between the experimental and numerical results are also made. |
