Interferencia de flujo entre cilindros circulares en disposición tándem cercanos al suelo

Abstract : This study focuses on the numerical simulations of the flow around two tandem cylinders placed near a wall. The cylinders are immersed in a flow with a boundary layer profile at a subcritical Reynolds number (Re=10000). The three-dimensional transient turbulent flow around the cylinders is simulated numerically using the Scale-Adaptive Simulation (SAS) turbulence model by means of the Fluent code. The effects of wake interference due to the proximity between the cylinders and the proximity with the wall are examined through the values of drag and lift coefficients. Also, the details of the flow fields in the near wake of the cylinders are analyzed. The results are compared with experimental and numerical results reported in the literature, as well as to the case of a single cylinder near a wall.
