Investigating the Dynamic Behavior of Loosely Supported Parallel Triangular Arrays Subjected to Two-Phase Flow
Abstract
Abstract Flat-bar supports have long been employed to control transverse fluidelastic instability (FEI) in steam generators. While they might be effective for transverse vibration suppression, large displacements in the streamwise direction may occur due to the presence of support clearances. The incident at the San Onofre Nuclear Generating Station (SONGS) illustrated that excessive streamwise tube motion can occur, leading to tube failures …
