Influence bend radius on multiphase flow induced forces on a bend structure
conference paper
Multiphase flow induced forces can result in large amplitude vibrations in flexible piping. In single phase, elongating the bend by increasing the bend radius is a valid strategy to reduce the forces. In this paper, multiphase induced forces on a 1.5D and 3.3D bend are compared for near-atmospheric conditions in a 0.15m diameter bend. In contrast to the single phase, the larger bend radius has equal to slightly higher forces. On average, the measured forces in the 3.3D bend are 25% higher than in the 1.5D bend.
