An Investigation on the Use of Venturi Weirs as an Aerator
, 2003 The most classic example of a hydraulic structure where gas transfer occurs is a weir. Transfer of gases between the atmosphere and river water can occur in a free overfall jet from a weir.

, 2014 本文係研究變擴形渠道之投潭水躍消能效率近似模式解析，爾後利用近似解經驗式作為演算主軸，建立一變擴形渠道堰壩投潭消能機制三維視窗化模組，以提供一快速且便捷之堰壩投潭消能效率估算與3D展示工具。近似解析所探討之水力參數包含共軛水深比ϕ、相對能量損失∆E/E_i及投潭水躍消能效率η。 研究結果近似模式與理論模式相較，其平均相對誤差δ ¯皆於可容許誤差±15%之範圍，驗證近似模式之適用性。而視窗化計算結果與前人試驗值相差甚小，顯示本文所研發之3D視窗化模組具實用性。 此外 ...
