Abstract

The pressure difference on various configurations of high structures is demonstrated in this study by numerical analysis using the ANSYS CFX package for wind incidence angle 0° and the k − ɛ model. Engineers may now simulate wind action around structure models to build high structures, resulting in the exponential growth of computational fluid dynamics (CFD) techniques in recent decades. To understand the differences in pressure variance, the flow patterns are discussed. Due to the merging of pressure and suction on the windward and leeward sides, unstable vortices emerge in the wake zone. The wind flow pattern around the structure shows the flow separation features and wake zones where vortices are formed. The model's plan layout and size were discovered to have a direct impact on the distribution of wind pressure on the model’s numerous faces during wind tunnel testing. The windward side of the atmosphere is positively pressurized in both scenarios.
