Abstract
The use of different sizes of cylinders in close space has been presented as an option to reduce the vibration amplitude of cylinders free to vibrate. This configuration can be reversed to increase the amplitude and allow energy harvesting. The present study aims to explore the flow over two aligned cylinders focusing on the fluid dynamic forces on the cylinders fixed and identifying the influence on the generating energy process. The numerical analysis is performed with a Reynolds number of 7.5 x104 and the space ratio equal to 2.67 for the tandem cases. The simulations were executed with the finite volumes method applying Reynolds Averaged Navier-Stokes (RANS) equations adopting the turbulence model
