In this thesis work, a 1 - d hydraulic transient model and a 2 - d compressible flow model with the large eddy simulation approach have been applied to analyse the hydrodynamic process of the unsteady separated flow. prototype observation data of gezhouba shiplock no. 3 has been used to verify the computational results. it has been found that two different types of flow regime - stably - varying and strongly - oscillating regimes - could occur in the radial gate tunnel
本文採取將一維非恆定流模型與二維可壓縮流一大渦模擬模型相結合的方法，分析了急變分離流的水動力學特性，並利用葛洲壩三號船閘的原型觀測資料驗證了數值模型的可靠性，發現閥門段存在平穩變化型和劇烈振蕩型兩種不同的流態，並詳細計算、分析了它們的流動特徵
