Vortex Induced Vibration Analysis of a Triangle Prism at Different Velocities
In this Paper the Flow-induced motion (FIM) and power conversion of triangular prism in cross-flow is numerically investigated using 2-Dimensional fluid domain with spring mounted oscillators and study the effects at wakes. Flow velocities between 0.05–0.15 m/sec, Reynolds number 2250–7500 and spring stiffness of 125 and 250 N/m are used for the simulation cases. The results show that in Vortex Induced Vibration (VIV) region the response of dynamic characteristics is high with a maximum amplitude and maximum power. The maximum amplitude of the oscillation, maximum co-efficient of lift force and displacement have been calculated mathematically for plotting a graph and theoretical and simulated efficiencies are compared for validation of the analysis.
