Active and passive control of a galloping cylinder with heat transfer

Wind energy caused the transverse vibration of the beam, and the mechanical energy of vibration is transferred to electrical charge by piezoelectric transducer. In the current study, the active and passive control of energy release from a galloping bluff body is found. The system consists of a bluff body in front of wind which is mounted on a cantilever beam and supported by piezoelectric sheets. The nonlinear motion of the Euler–Bernoulli beam and conservation of electrical energy is modeled by lumped ordinary differential equations. The wind force on bluff body is modeled by moving mesh techniques in OpenFoam software where the fluid and solid corresponding dynamics are connected in timescales. The position of piezoelectric actuator and the location of bump are the two parameters considered for optimization analysis of galloping device. Genetic algorithms are used to find the optimal arrangements. Numerous models are offered for a clamped−clamped supported beam.
