| Summary, etc. | The effect of high Reynolds Number on flow induced vibration of a rotating circular cylinder<br/>vibrating in transverse direction using RANS model is investigated by solving two dimensional<br/>Reynolds Averaged Navier Stokes (RANS) Equation using SST K-Omega model and PetrovGalerkin (PG) finite element method. One dimensional numerical simulation has been performed<br/>in which rotating cylinder is allowed to vibrate in transverse direction using three rotation rates<br/>(α) 0, 0.5 and 1 and two Keulegan Carpenter (KC) numbers 5 & 10 against each rotation rate.<br/>Wide range of Reduced Velocities (Vr) ranging from 1 to 15 are used to determine the effect of<br/>high Reynolds Number (Re) 5000 on flow induced vibrations of a rotating and vibrating<br/>cylinder. Mostly regular vibrations for KC =10 at all rotation rates. The vortex shedding starts<br/>with the single vortex being shed after two flow cycles for Vr < 3, the vortex shedding changes<br/>to one vortex being shed in one complete flow period as the reduced velocity is 4 till 6. For Vr ><br/>7 vortex are shed in one pair regime and as the reduced velocity reaches 10 the amplitude of<br/>vibration increases significantly due to the positive vortex attachment with the surface of the<br/>oscillatory cylinder. The magnitude of peak frequencies is less for KC = 5 as compared to KC =<br/>10 and increases with the increase in reduced velocity and by increasing rotation rate. The<br/>frequency component of vibration becomes one times the frequency of fluid as Vr > 2 for KC =<br/>5 and Vr > 5 for KC = 10. The significant increase in the amplitude of vibration shows the<br/>mechanical energy presence through which energy can be harvested by generating very less<br/>power. The correlation of amplitude of vibration and vortex shedding associated with vibrating<br/>and rotating cylinder is studied. |
