Abstract
The present numerical simulation is carried out to evaluate the effect of Richardson Number on cylinder displacement and in turn the power extraction from the movement of cylinder. An in-house code based on arbitrary Lagrangian Euler scheme is used to tackle fluid structure interaction. The following fluid parameters is used in a present study Reynolds Number (Re) = 100, Prandtl Number (Pr) = 7.1 and Richardson number (Ri) = [-1, 0]. Structural parameters are as follows Reduced velocities (Ured) = 3 and 8, Reduced mass (Mred) = 2, damping coefficient (ξ′) is set to be zero. With the aid of thermal buoyancy there is significant increase in power is obtained.
