摘要
本文从N-S方程出发,结合我们已取得的弯曲河道三维水流数学模型研究成果,对弯曲河道分凸岸区域和凹岸区域分别建立了横向压力分布计算公式,说明横向压力分布仅在凹岸区域服从抛物型,进一步证实了弯道流动为一种典型的部分抛物型流动。
In this paper based on N-S equation and the results of three-dimensional flow model of channel bends, the formulas of the transverse pressure distribution are found in the inner bank region and the outer bank region respectively. The results show that the transverse pressure distribution is parabola-type only in the outer bank region. This proves further that flow in channel bends is a kind of typical partial parabola-type flow.
