| Summary: | 碩士 === 淡江大學 === 水資源及環境工程學系碩士班 === 100 === In this study use the model and simulation analysis of discharge-water stage relationship at dam-break site. The dam-break model to placed on straight channel downstream. The experiment was conducted in flume 12.00m long, 0.775m wide and 0.7m high with bed slope=0.001. Shape of dam-break is rectangular. Dam is divided into three levels, the first level is the shape of dam-break, the second level is the gate and the third level is the vertical sliding gate. The test set residual dam W=0.250m high, W=0.166m high, W=0.125m high, W=0.100m high and no residual dam.
In this study use the FLUENT to establish the unsteady flow numerical model. Simulate the dam-break by turbulence model based on three-dimensional model. The simulation conditions and model conditions are the same. Comparative and analysis of simulation and experimental results.
