摘要：
Turbulent flow parallel to fuel rod bundles arranged in a triangular array are computed musing 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.
