【摘要】 采用相同的边界条件、不同的湍流模式对三峡真机尾水管进行了CFD数值解析,并对结果进行了比较。由于不同的湍流模式在模化过程中考虑的侧重点不同,因此计算的结果也有很大的差别。在尾水管动态计算中采用非定常雷诺应力湍流模式是比较合理的。更多还原

【Abstract】 This paper numerically simulated the draft tube of the Three Gorge’s prototype power unit using similar boundary condition and different turbulence models and compared the results. Additionally, this paper analyzed the considerable difference during the course of modeling using different turbulence model which produced the different results. It is reasonable to use the non-steady RNS turbulence model for simulating dynamic flow of draft tube.更多还原
