摘要:
为了消除控藻井工程对泵站进水流态的不利影响,基于CFX软件,运用雷洛时均N-S方程和RNG k-ε湍流模型,结合多种控藻井布置形式和泵站进水侧整流措施,研究泵站进水侧三维流动形态及特征断面上水力参数。通过结果可知,一字型导流墙不适合正向进水条件的泵站整流,两道底坎方案时水流条件最佳,前池整体流速控制在0.95 m/s以内,水流流态较为平顺,3台机组进口断面流速接近,湍动能数值较低,流速均匀度数值较原始方案平均提高了10.7%,速度加权平均角度平均优化了4.6°。
Abstract:
In order to eliminate the adverse effects of algae control well engineering on inlet flow regime of the pumping station, based on CFX software, the three-dimensional flow regime of the pumping station intake side and hydraulic parameters on the characteristic section are investigated by applying the Lei Loh time-averaged N-S equations and the RNG k-ε turbulence model in combination with a variety of algae control wells arrangement forms and pumping station intake-side flow rectification measures. It can be seen from the results that the one-type guide wall is not suitable for the rectification of the pumping station with positive inlet conditions, and the water flow conditions are optimal in the case of the two-bottom-can scheme, with the overall flow velocity of the forebay pool controlled within 0.95 m/s, the water flow regime is smoother, the flow velocity of the three units in the inlet section is close to the same, and the turbulence kinetic energy values are lower, the flow velocity uniformity values are increased by an average of 10.7% compared with that of the original scheme, and the velocity-weighted average angle is optimized by an average of 4.6 °.
