Numerical Investigation of Wind Pressure Coefficients on Different Scallop Dome Configurations

The effects of the action of wind on scallop domes were numerically investigated using the software Ansys, as well the interference of the neighborhood on the external pressure coefficient and the streamlines between geometrically identical domes. The influence of the proportion on the neighborhood interference in scallop domes and the variations in the dimensions of the structures on the pressure coefficients and streamlines were also investigated. Five simulations were analyzed involving six-grooved domes and geometry height variations for validation. The numerically obtained coefficients were compared with values in the literature. Other applications investigated the influence of grooves on the external pressure coefficient and the effect of wind on the grooved domes. Another application analyzed the interference of the neighborhood on the external pressure coefficients and streamlines between three geometrically identical domes and, finally, the influence of the proportion in the study of the interference of the neighborhood. Here, the variations in the dimensions of the structure affected the pressure coefficients and the streamlines were analyzed. It was possible to verify the versatility and efficiency of the computational method used in the analysis of the action of wind.
