Abstract
Despite the benefits that can be obtained, and the growing number of studies carried out in recent years on the Magnus effect, no relevant studies on the response of this effect in simulations considering different turbulence models has been found. In this work, numerical investigations will be carried out on the observed effects on the behavior of stationary and rotating cylinders in a uniform flow field, considering the classical and widely applied turbulence models such as k-epsilon, k-omega, and its variant k-omega SST; generally called the RANS - Reynolds Average Navier-Stokes. Also, will be used the DES (Detached Eddy Simulation) modeling that combines the LES (Large Eddy Simulation) and RANS models. That is applied to zones of separation and highly adverse pressure gradient while this is used for the remaining flow. In addition to consider the different models, the dimensional scales that best meets the proposed problem will be verified. The simulations will be carried out for conditions of a Reynolds number 100 and 1000, for two-dimensional models, and the results will be compared with experimental data obtained in several other studies. The results have not been shown to be favorable solely to one model of turbulence.
