Abstract

The flows around two circular cylinders in tandem arrangements at a subcritical Reynolds number are numerically investigated. The center-to-center space of the cylinders is varied from twice the cylinder diameter to five times that, and the flows and fluid dynamic forces obtained from the simulations are compared with those in the literatures involving experimental investigations. Special attention is paid to the characteristics of the vortices shed from the upstream cylinder such as the convection, the impingement onto the downstream cylinder and the interference with the vortices from the downstream cylinder. The effects of the vortices from the upstream cylinder on the fluid dynamic forces acting on the downstream cylinder are discussed.
