有鑑於先前文獻在旋轉冷卻通道中之熱傳量測多採用熱電耦量測，以提供區域性平均值，而無法提供局部熱傳分佈資料，以及鮮有文獻報導旋轉管道中之局部壓力分佈數據，本研究乃分別以暫態液晶熱傳量測技術與壁面壓力量測法，對渦輪機葉片內冷卻流道進行局部熱傳與壓降分佈量測與分析。實驗的管道為一具有180度急彎的矩形管道，管道之水力直徑為22mm，且具有正45度攻角肋條與尖角朝上游45度V形肋條兩種型式之肋條，本文結果並與文獻中常用之90度攻角肋條比較。實驗的雷諾數固定在104，旋轉參數變化範圍於0與0.2之間，空氣為工作介質。
熱傳量測結果發現就管道之整體熱傳增益而言，旋轉參數Ro存在一臨界值Rocr：在此一臨界值時，所比較之三型肋條管道之整體熱傳增益值皆最低；當Ro<Rocr時，三型肋條管道整體熱傳值隨Ro增加而降低；而當Ro>Rocr時，三型肋條管道整體熱傳值隨Ro增加而增加。在接近渦輪機操作狀況之Ro值時（即Ro=0.20），管道之整體熱傳增益排序依次為（90度攻角肋條管道）>（尖角朝上游的45度V型肋條管道）>（正45度攻角肋條管道）。然而就管道局部熱傳分佈之均勻性而言，其排序恰與上面之整體熱傳增益排序相反。

管道壁面壓力量測結果顯示，旋轉對所檢視的三型肋條管道之整體壓損影響很大。亦即管道壓損隨Ro增加分別呈現漸增或漸減或鋸齒狀；其壓損排序由大至小依次為（具尖角朝上游之45度V形肋條管道）>（具正45度攻角肋條管道）>（具90度攻角肋條管道）。文中亦討論離心力對加裝所檢視之三型肋條在第一流道的壓降影響。
