【摘要】 采用有限体积法/Osher格式,通过对冲积河流平原河段枢纽上下游水沙二相流的特点和边界条件的分析,建立二维水沙数值模型。对塔里木河乌斯满水利枢纽上下游进行模拟运算,其结果与物理模型实测数据相吻合,证明了有限体积法Osher格式模型的模拟的可行性和合理性。更多还原

【Abstract】 A two-dimensional numerical water-sand model was built with Osher scheme on the basis of analysis of the characters and boundary conditions of water-sand two-phase current of flatland river section of alluvial river,The simulation operation of the upstream and downstream of Wusiman Hydro Project along the Tarim River was conducted.The final test results were found to be identical with the data obtained by physical model,which revealed that the simulation of Osher schem was reasonable and practical.更多还原
