摘要:

利用边界元法求解悬板分层式引水渠道的悬板区过流问题 .根据自由水面和流量迭代过程中相互影响的关系 ,提出了两者同步迭代的方法 .数值计算表明 ,这种迭代方法对流量和自由面初值没有苛刻的要求 ,且具有较好的收敛性能 .计算结果与实测结果吻合良好

Application of boundary element method in stimulating flow over plate region

SUN Tao¹,QIU Xiu-yun²,ZHOU Zhu²

Abstract:

The boundary element method for calculating the free surface flow over the hanged plate region of the two storied intake work is presented in this paper. A synchronous iterative method for the discharge and the free surface is presented according to the interaction between them. This method has no strict requirement for the initial value of the discharge and the free surface according to the calculation. It has good convergence and there is good agreement between the numerical results and the measured ones.

Key words: boundary element mehtod,free surface,iteration,two-storied intake work,hanged-plate,
