One of the main problems associated with steam generators is excessive tube vibration caused by turbulent flow buffeting and fluid-elastic excitation. This vibration can lead to the rupture of the tubes within the steam generator, causing reduced availability due to tube plugging, and can eventually force replacement of the steam generator. The fluid/structure interaction that causes fluid-elastic excitation is unknown at this time, but it is believed that turbulence buffeting and resulting excitation is one of the mechanisms leading to tube vibration. The large-eddy simulation (LES) technique is being considered as a possible design analysis tool for defining the temporally fluctuating forces on steam generator tube banks. The investigation describes in this paper utilizes LES in calculating the flow field for a square pitched tube array in cross flow. A good comparison has been obtained between calculated and measured values of the power spectral density (PSD) of the lift and drag forces.
