Abstract EN
This paper focuses on fluid forces acting on a confined cylinder subjected to axial flow in application to fuel assembly dynamic behavior.
From the literature, it is difficult to estimate the damping induced by the flow.
Therefore, it is proposed to study numerically the damping fluid forces on a cylinder for various parameters.
It has been observed that it increases with the smaller confinement and with the presence of an obstacle and decreases when the Reynolds number increases.
Larger values correspond to a greater contribution of pressure forces.
Dynamic simulations are compared to the steady ones and give different values, but the order of magnitude and general trend remain the same.
Therefore, steady simulations are suitable to have a rough estimation of drag coefficients in dynamics.
