采用大涡模拟和混合RANS/LES方法计算了平行于三角形燃料棒束的湍流流动。通道内的流动脉动被捕获和主频率是与实验一致的。混合方法在近壁区域显示出缺乏准确性，这可能是由于混合函数的制定。
Turbulent flow parallel to fuel rod bundles arranged in a triangular array are computed using LES and hybrid RANS/LES. Inner-channel flow pulsations are captured and the dominant frequency is in agreement with the experiments. The hybrid method shows a lack of accuracy in the near wall region probably due to the formulation of the blending function.
