开敞水域中斜跨航槽水流的流速计算

通过理论分析,运用试验数据,对开敞水域航槽中心垂线平均流速变化规律进行探讨,同时给出了航槽中心垂线平均流速的计算公式。在表达式中,边坡采用了比以往幂函数更为合理的指数函数形式。最后,用水槽试验数据对所得公式进行必要的验证,计算值与实际值吻合较好。

Velocity Computation in a Navigation Channel at an Oblique Angle to Flow Direction in Open Waters

Based on the theoretical analysis and experimental data, this paper studies the regularity of the variation of velocity in the navigation channel when the flow crosses the trench at an oblique angle to flow direction in open waters. An empirical formulation of the velocity in the navigation channel is derived as well. In the empirical formulation, side slope adopts exponential function, which is better than the previous power function by comparison. The result of the computation reveals close agreement with the flume experiment data.
