A Wind Tunnel Experiment on Viscous Drag of a Body of Revolution

Abstract

In order to investigate into the characteristics of viscous flow field around a body and its viscous drag in high Reynolds number, the measurement of surface pressure and the velocity and pressure in the boundary layer and wake has been attempted for a body of revolution of length 4m in a wind tunnel. The experiment has been made at the wind speed 15-35m/s. Pressure drag is obtained from the measured pressure distribution and frictional drag is from the velocity distribution in the boundary layer. Discussion is made on the comparison of the results with existing data.
