Abstract
Computational fluid dynamics (CFD) is a useful tool that is currently integrated into the industry at large. It is used for maintaining, designing, operating, and analyzing equipment or structures in contact with fluids, such as wind impacting tall buildings. Additionally, it encourages engineering innovation through simulators that help studying flow behavior. This work was conducted to assess the accuracy of CFD simulations compared to experimental studies, such as wind tunnel tests and full-scale studies. Based on data from a study by Kikuchi et al. (2024), where wind pressure samples were taken from the surfaces of a tall building, a model was created using CFD simulations, and the results were contrasted with the experimental data. The findings show that polyhexacore meshing reduces computational costs and attains 92% accuracy relative to experimental studies, which signals its efficiency in wind assessments in buildings.
