A study was conducted to anlyze the flow induced vibration due to internal multiphase flow. The approach uses the Abaqus co-simulation feature in STAR-CCM+® to fully couple the fluid dynamics of the internal VOF flow to the Jumper structural mechanics. This study focuses on the internal flow and assumes the Jumper external flow is quiescent. Several different simulations were conducted
The consequences of various assumptions regarding “added mass and added damping” applied in the one-way coupled solution may then be evaluated by comparison to the fully coupled solution particularly in terms of fatigue.
