【摘要】 在开展某泵房水工模型试验时发现,该泵房的前池设计虽较合理,但池内流动紊乱,究其根源在于前池进流配水均匀性不佳．在将前池上游的矩型进水箱涵改为扩散型箱涵后,经水工模型前池流态观测和流场对比试验验证,前池流态得到了显著改善．更多还原

【Abstract】 During testing on a pumping station model,it was found that although the collecting basin was designed to be reasonable,the flow pattern in the basin was awfully bad.Having replaced the upstream inflow box culvert with constant rectangular section by a divergent one,the results of flow pattern observation and flow field measurement in the collecting basin show that the uniformity of flow field in the basin is improved remarkably.更多还原
