首发时间:2009-06-25
摘要:本文以fluent流体计算软件为平台,通过采用不同的紊流模型与差分格式对抽水蓄能电站侧式进/出水口进(出)流工况水力特性进行数值模拟。通过数值模拟结果与试验结果的对比,分析比较不同的紊流模型和差分格式对计算结果的影响,结果表明,只要选用合适的紊流模型与差分格式,数值模拟方法作为研究抽水蓄能电站侧式进/出水口水力特性的补充验证手段,减少物理模型试验的复杂程度,缩短研究周期是可行的。

The research of effect in the numerical simulation of lateral inlet\\outlet
Abstract:On the basis of the fluent software, the flow was simulated using different turbulence model and difference format in the lateral inlet\\outlet of pumped storage plant. By analysising and comparing the results caculated by numerical simulation with model experiment, the calculation can be made that the feasibility of using appropriate numerical simulation as a measure to research the hydraulic characteristics of lateral inlet\\outlet, and to reduce the complexity of the model experiment and periodic time of study were proved.
Keywords: lateral inlet/outlet numerical simulation turbulent model difference format
