侧式进/出水口顶板扩张角对拦污栅断面流速分布影响规律研究OA北大核心CSTPCD
Study on the influence of the expansion angle of the side inlet/outlet roof on the velocity distribution of the trash rack section
抽水蓄能电站侧式进/出水口双向过流,其顶板扩张角的大小将直接影响拦污栅断面流速分布是否均匀,甚至出现反向流速.抽水蓄能电站设计规范将3°～5°作为侧式进/出水口顶板扩张角的推荐范围,其依据是矩形渐扩管阻力系数最小的扩张角度,但侧式进/出水口体型较之复杂很多,因此有必要进一步探讨.本文以某侧式进/出水口体型为研究对象,采用数值模拟方法,研究了 11种角度的顶板扩张角对出流工况和进流工况拦污栅断面流速分布的影响.结果表明:在出流工况下,随着顶板扩张角…查看全部>>
The two-way flow of the side inlet/outlet of the pumped storage power station,the size of the roof ex-pansion angle will directly affect the uniformity of the flow velocity distribution of the trash rack section,and even the reverse flow velocity.The design code of pumped storage power station takes 3°～5° as the recommended range of expansion angle of side inlet/outlet roof,which is based on the expansion angle with the smallest resistance coef-ficient of re…查看全部>>
