Estudo experimental do escoamento sobre uma esfera

Abstract

The analysis of flow over a sphere provides important information for industrial processes involving aerodynamic forces on spherical bodies in laminar and turbulent flows. This study used a Pitot tube to measure the flow pressure in different positions, varying every 25 mm. The AA-TVCR3 pressure module, integrated into the ’Aeroalcool – Wind Tunnel’ software, was used to obtain the pressure differential in each position. The sphere, made of polymer with a diameter of 89.5 mm, was positioned in the center of the test section of the wind tunnel. The pressure values were used to determine the flow speed and compare with the values obtained in Tyagi’s study, verifying the accuracy of using the Pitot tube in turbulent flows.
