dc.description.abstract | 摘 要
本文利用可隨溫度值不同而改變其反射顏色,且懸浮於流場中之感溫液晶粒子(Thermochromic Liquid Crystal traces),結合影像處理,成功建立可量測流場內二維切頁之溫度場的技術,稱為液晶顯像測溫技術(Particle Image Thermometry)。在不影響原流場結構的前提之下,除了可量測流場內瞬時溫度值外,還可結合質點顯像測速儀(Particle Image Velocimetry)的計算,得到流場之速度。本文內容詳細介紹,此技術之原理、實驗設備架設、校準及實驗方法建立,並將此技術應用於,以水為工作流體之具溫度差渦環流場的量測,分別就冷、暖渦環,加以分析其溫度、速度與渦度等物理量之分佈與變化情形,驗證此量測技術之實用性,及加以探討此具溫度差之渦環流場的物理特性。 | zh_TW |
dc.description.abstract | Abstract
A technique called particle image thermometry (PIT) is developed that enable to visualize 2-D temperature field using suspending thermochomic liquid crystal traces (TLCs) in water. TLCs reflect different colors with different temperature. PIT can not only visualize qualitative temperature filed but also quantify the temperature value with digital image process. Combing with particle image velocimetry (PIV), this technique can simulate measure temperature and velocity field. In this paper, the technique theory, experimental set-up, calibration and procedure has been described. The study shows the applicability of PIT/V in vortex ring with thermal difference. It demonstrates that PIT/V is a helpful tool for analyzing vortex ring structure with heat transfer. | en |
