| Sumario: | The experimental study of the pressure distribution around an obstacle formed by four cylindrical tubes of three different diameters immersed in a transversal flow and at different inclination angles with respect to the flow was carried out. Air at atmospheric pressure was used with a maximum flow of 0.038 Kg / sec. For each cylinder bore and spacing, the pressure distribution is strongly influenced by the angle of inclination, but only marginally affected by flow (within the working range). Due to the turbulent condition of the air flow, with a Reynolds number in the separation between bars from 1695 to 5100, a very good agreement was obtained between the experimental results and a model based on the average air speed in that space, better than a model based on the curvature of streamlines in the gap. |
