Abstract:	本研究應用模型試驗及數值模擬分析明渠流於臨岸系列圓柱之能量損失，試驗之模型置於底床波降S0=0.003、長10.50m、寬0.39m與渠壁深0.19m之直線渠道。於渠道中放置一至九根圓柱，圓柱寬為3.4cm與4.0cm、圓柱心距為14.0cm，並設定不同邊界條件以模擬各種福祿數下系列圓柱之能量損失。本研究利用FLUENT商業軟體建立非恆態流之模式，以紊流模式依據三維模型進行模擬，其模擬條件與試驗條件相同，並將模擬結果與試驗結果比較分析。 This study uses the model and simulation to analyze the Energy Loss for series cylinders along channel bank in Open-Channel Flow. The test model to placed on straight channel. The experiment was conducted in flume 10.50m long, 0.39m wide and 0.19m high with bed slope=0.003. Placed in the channel one to nine cylindrical,cylinder width of 3.4cm and 4.0cm,cylindrical center distance is 4.0cm The test set Different boundary conditions up to Energy loss of series cylinder under various Froude numbers. This study uses the FLUENT to establish the unsteady flow numerical model. Simulate with turbulence model based on three-dimensional model. The simulation conditions and model conditions are the same. Compare and analyze simulation and experimental results.
