Abstract

Numerical simulation for vortex-induced vibration (VIV) of a 2-DOF cylinder with mass ratio of 2.6 was conducted using the PimpleDyMFoam solver based on OpenFOAM and adopting the k- SST turbulent model proposed by Mental. Three initial conditions including constant acceleration, constant deceleration and constant speed were employed in simulation. The results showed that the hysteretic phenomenon appears in VIV of the cylinder in a "numerical water pool", the hysteretic interval is 〖6≤U〗_r≤6.8; when Ur is 6 or 6.8, the phase switching phenomenon is captured through the relation between lift and displacement; constant acceleration and constant deceleration conditions can capture the super-upper branch, while constant speed condition misses the upper branch; when Ur = 6.8, the constant acceleration condition can get the maximum amplitude 1.4D; when adopting constant speed condition without hysteretic effect, the maximum vibration amplitude of the cylinder is only 0.85D; three initial conditions all lead to locking phenomenon, but their locking intervals are different; with constant acceleration and constant deceleration conditions, 2T mode is successfully simulated; with constant speed condition, only 2P mode is simulated; through analyzing contrastively wakes’ varying law in hysteretic region, the hysteresis mechanism is presented; when adopting constant acceleration initial condition with a smaller acceleration, the phase switching is delayed.
