- 中文摘要: 本報告包括兩部份,第一部份為空泡流動壁面效果之研究,利用自由流線理論,以保角變換,在理論上分析閉塞流動(Choked Flow)情況下,純阻力性楔形物體之非粘性壁面效果,並配合邊界層理論而討論其粘性壁面效果。第二部份為空蝕水槽實驗技術之探討,其內容為螺漿模型之製造、尾流模擬,相似法則,液體之物理性質,壁面效果,以及空蝕水槽之試驗方法。
- 英文摘要: This report consists of two parts. The first part is a study on walleffects of cavity flow. Free streamline theory is used to solve the chokedcondition of a symetric wedge in two parallel walls, and theoretical solut-ion is found. Additionally boundary layer theory is used to discuss theviscous wall effects of a water tunnel. The second part is concerned withsome experimental techniques of cavitation tunnel. And a wake rake ismade in order to simulate the actual flow conditions around the propeller.
