摘要
本文从纳维埃斯托克斯方程式出发,应用贴体坐标变换,推出了计算溢流坝面反弧段压力分布准三维的精确方法,且用差分法进行了数值解。该方法和有限元法相比,具有计算简单、时间短、易于收敛的优点。
Starting from the N-S equations and with coordinate transformation method, this paper develops an accurate 3-D model for computing the pressure distribution on spillway. The model given by this paper solves the equations with a FDM. The method above has a quality of short CPU time, easy calculation and good convergence compared with FEM developed by former researchers.
