In this paper, a boundary element method is presented to solve the Ω-ψ equation of two-dimensional flow of incompressible viscosity. The boundary integral equations for determining stream function ψ, and vortex function ω are derived mathematically. These equations are also discretized and solved on the boundary of a calculated area. The result of a calculating sample of two-dimensional divergent canal flow shows that this method is a more effective way in calculating two-dimensional viscous flow....

In this paper, we discuss the characteristics of the hydraulic cross section and derive a for- mula rof calculatiog the geometric dimensions and the hydraulic properties for the best cross section with trapezoid-arc form. We show that compared to the commonly used trapezoidal shape of the hy- draulic cross section, the trapezoid-are section is more economic; has better side slope stability; and re- duces the sedimentation and alluvial of the canal flow. Therefore it is worth extension and application in practice. To make the design easier, we also tabulate different parameters for calculating the dimen- sions of the best hydraulic cross section with trapezoid-arc form in various side-slope coefficients. At the end, we give an example of using these tables.
