摘要
采用二维非恒定流方程为基本控制方程,运用有限元法建立复杂河道的二维水流数学模型,并应用于福州市大学新区溪源溪下游河道.计算结果表明,数学模型计算值能够较好的吻合实测值,能正确反映河道的水位、流量变化过程,很好地复现河道的水流形态.
A two -dimensional flow mathematic model for the complicated channel, which is apphed to the downstream channel of Xiyuan brook in the new districts of Fuzhou university, is established by using two - dimensional unsteady flow equations as the basic control equation and the finite element method. The calculation results show that the mathematical model, of which the calculated values can better agree with the measured and accurately reflect the water level and flow＇ s change processes, can be used for study on water flow movement rule of fiver regulation scheme and flood control and drainage system.
