Abstract

Two dimensional numerical simulations are performed to investigate Flow-Induced Vibrations (FIV) of a circular cylinder, subjected to an oscillatory flow at a Reynolds number of 5000, using the Reynolds-averaged Navier-Stokes (RANS) equations coupled with the SST k-ω turbulence model. The cylinder is allowed to vibrate only in the transverse direction, at three different rotation rates of α = 0, 0.5 and 1, two Keulegan Carpenter numbers of KC = 5 and 10. A range of reduced velocities from Vr = 1 to 15 is considered for the study. The results showed that the amplitude of vibrations increases with increase in the rotation rate for the entire range of reduced velocities. The lock-in regime which is defined as the range of reduced velocity where high amplitude is observed is widened when α = 0.5 and 1. The vortex shedding behavior is observed to be significantly dependent on Vr. Overall, the observed vortex shedding patterns differ from the usual flow patterns observed for a non-rotating or a non-vibrating cylinder.
