Top tensioned risers (TTRs) and steel catenary (SCRs) have been widely used in the field of marine engineering. They are commonly to transport fluids from subsea wells surface platforms. Under action ocean currents, these often subjected vortex-induced vibrations (VIVs), which might lead serious fatigue damage. In this study, VIV around TTR SCR were numerically simulated using computational flu...

the steger and warming flux vector splitting implicit scheme is used to numerically solve two dimensional reynolds averaged navier–stokes (rans) equations governing the vortex induced vibration of a flexible riser laterally supported by a spring and a damper. the k–ε model is used as turbulence model to simulate the turbulent flow in the wake of the riser. to update the new position of the rise...
