本研究成功地開發經由懸浮於流場中之液晶粒子之顏色反應來獲得溫度場資訊之質點影像測溫儀 (PIT)並應用此 PIT 探討由單一氣泡尾流所引發之局部熱傳效應的增強機構。本 PIT 技術之核心在於透過溫度與 Hue 值之仔細校正而使能因溫度變化而改變顏色之液晶粒子影像可重複、正確地顯示流場中溫度場的變化。再經由溫度及溫度梯度等高圖之展示可對流場結構及熱傳機構提供更近一步之了解。此液晶質點影像測溫儀亦可適度地作為絕佳之流場觀測工具。A Particle Image Thermometry (PIT) based on the extraction of the temperature field from the color response of the suspended liquid crystal particles in the flow has been successfully developed and used to the study of the heat transfer enhancement induced by bubble wake in a two-dimensional bubble column. The change of the temperature field of the flow can be displayed correctly through careful calibration between Hue value and temperature. Thorough understanding of the flow structure and the heat transfer mechanism can be obtained through the exhibition of temperature and temperature contours.
