Two-phase Flow pattern Observations and Pressure Drop Measurements at the Sudden Flow Area Expansion in Small Rectangular Channels
碩士 === 國立雲林科技大學 === 機械工程系碩士班 === 95 === 針對目前高效率電子設備為了發展散熱技術,常會使用密集式熱交換器,在密集式熱交換器等此類的相關相關元件中,因應逐漸微小化的電子設備本體,會於有限的空間內前後對應的長方形流道通常用一個突擴、突縮段來做連接,然而目前只有一些單相流壓力變化和熱傳的論文發表過,關於微小流道的壓力驟變相關的研究卻很少被提出討論,甚至於兩相流體流過突擴、突縮段的研究都沒有發現,因此本研究的目的就是要探討在此突擴段內的兩相流摩擦壓力變化關係和流型與其相對的變化。 此實驗將用透明的壓克力板做成帶有突擴段的長方形流道以方便觀察兩相流流型的型態,這些測...
