Wind Analysis on Pentagonal Cylinder by Using Low Speed Subsonic Wind Tunnel

Mohanraj.N


Abstract: In this present work experimental investigation of wind effect on a pentagonal cylinder was carried out. The test was performed on the single pentagonal cylinder in a open circuit wind tunnel at different cases of Reynolds numbers from 57300 to 133700 or different inlet velocity of air from 15m/sec to 35m/sec. The surface static pressure head at different locations of the cylinder were measured with the help of multitube manometer. The pressure coefficients were calculated from the measured values of surface static pressure head on the cylinder. The drag coefficient and drag force are obtained from the pressure coefficients by the numerical integration method. These results will help the engineers to design the building in conservative way. The results obtained in this present work can be adopted for real life structure by multiplying with the scale factor if the conditions were well suited with the experiments.
