Numerical Simulation of Vortex-Induced Vibration of Submerged Floating Tunnel Cable

Abstract:

A two-dimensional RSM turbulence model combined with enhanced wall function method is used to solve Naviar-Stokes equations，and Fourth Order of Runge-Kutta method is embedded in FLUENT’ UDF for Solving vortex-induced vibration equation of the cable of the submerged floating tunnel .The weakly coupled fluid-structure interaction algorithm is applied to solve the vibration equation and Naviar-Stokes equations, respectively,and the structure systems and fluid systems are combined with the lift coefficient, drag coefficient and dynamic mesh technology. The following conclusions: submerged floating tunnel cable presents non-locking and locking the two phenomena with the increase of the reduced velocity; In the non-locking region, the cable vibration beat phenomenon; in the locked region, vortex frequency is closed to the natural frequency of the cable and vortex-induced resonance leads to a significant increase of the cable displacement and the lift and drag.
