The separation performance of yeast suspension using hydrocyclone
, 2015 碩士本研究分別以10 mm大小的水旋風分離器來進行實驗，並以單支及串聯連接進行酵母菌懸浮液之分離，探討進料速度、壓力、分流比等操作條件對分離效率的影響。並比較活性污泥及乾芒草粉的實驗結果，了解水旋風分離器在生化分離上的應用。 在分離酵母菌懸浮液時，實驗結果顯示，總分離效率會隨著進料速度或分流比的增加而增加。在進料速度12 m/s下，當分流比自0.4增加至10，總分離效率會增加3倍。而在單支及串聯連接下的分級曲線也會隨著分流比的增加而上升。 活性污泥在進料速度12 m/s時，將分流比的數值從0.4增加至5.

Mathematical simulation of hydrocyclones
Applied Mathematical Modelling, 1987 Abstract Cyclones are used widely in industry as classifying devices. Due to the complexity of the multiphase flow field in such a device, prediction methods are at best semiempirical and geared towards predicting overall performance parameters. This article presents a real alternative, using state-of-the-art numerical techniques to address the ...

Study of hydrocyclone and developing of membrane hydrocyclone
, 2010 碩士本實驗採用直徑30 mm之水旋風分離器，使用馬鈴薯澱粉當粉體，分別進行實驗和模擬的分析，實驗方面探討不同進口壓力下和溢流管深淺之影響，分析溢流和底流的粒徑分佈以及分離效率，模擬方面以多相流VOF模式模擬空氣核心並分析流場，以實驗與數值模擬為基礎，進而發展新樣式水旋風分離器-薄膜水旋風分離器。 實驗結果顯示，當進口壓力越大則整體分離效率越好。在不同溢流管深的實驗結果顯示，不管任何溢流管的深淺皆會因進口壓力增大而分離效率有所提升，以溢流管深為30 mm最理想。本研究的薄膜水旋風分離器在相同的操作條件下 ...

New method for extracting microplastics from sediments using a hydrocyclone and sieve
Results in EngineeringBecause sediments act as sinks for microplastics, various methods have been developed to extract microplastics from sediments; however, these methods are labor-intensive and expensive, thereby limiting their scalability.
