Abstract

A simulation study of wind loading on a group of octagonal cylinders with various longitudinal spacing is presented here. This simulation was carried out arranging two cylinders with same hydraulic diameter, placing one in upstream and one in downstream at uniform flow velocity 13.2 m/s using ANSYS 16. The surface static pressures at different locations of the cylinders were predicted for different longitudinal spacing with the help of computational program in terms hydraulic diameter (D) of the cylinder across flow direction ranging from one to eight times. Pressure coefficients were calculated from the static pressure distributions. It was observed that the drag coefficients are considerably smaller compared to those for a sharp-edged square cylinder and wind loading on a single structure is more severe than when it is a part of a group. The findings confirm the previous experimental works in similar arrangement of a group of octagonal cylinders.
