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 (U red ) = 3 and 8, Reduced mass (M red ) = 2, damping coefficient (ξ′) is set to be zero. With the aid of thermal buoyancy there is significant increase in power is obtained.
