NUMERICAL AND EXPERIMENTAL VISUALIZATION OF THE FLOW OVER BLUFF BODIES
RESUMO
The flow around several bluff bodies is studied both numerically and experimentally. The flow is simulated using a mixed Eulerian–Lagrangian numerical algorithm based on Vortex Methods. This method allows the study of the unsteady flow dynamics by using instantaneous numerical velocity and vorticity fields. However, only the mean two-dimensional flow is analyzed in this paper. Furthermore, experimental flow visualization using laser light sheet and Particle Image Velocimetry are performed on the same geometries inside a water channel. Several configurations are studied at different Reynolds numbers and a comparison of the numerical results with the experimental results is presented. The numerical results show good agreement with the experimental results and with other studies.
