Abstract:

A simple system of VIVACE (Vortex Induced Vibration Aquatic Clean Energy) was investigated based on the numerical modeling of VIV. The numerical solution of two dimensional Reynolds Averaged Navier–Stokes (RANS) equations is obtained for a circular cylinder laterally supported by a spring and a damper and free to oscillate in the transverse direction to determine the amplitude of oscillation for a given diameter of cylinder. The Steger and Warming flux vector splitting implicit scheme is used to solve the governing RANS equations along with an appropriate turbulence model of k- ε. Comparing the numerical results by other valid results such one presented in [1], the proposed numerical solution was able to provide fair results in terms of lift coefficient and amplitude of oscillation. Faraday’s electromagnetic law of induction was employed to calculate the harnessing energy from the system. FFT analysis was done on the non- dimensional amplitude from which the main period of transverse oscillation required in governing formulation was collected.
