A comprehensive study of the aerodynamic characteristics of an aspect ratio of 6.25:1 inclined square prism

Inclined prismatic structures have grown in popularity civil engineering due to increased architectural and aesthetic demands, leading a surging need study their aerodynamic properties. In this study, an inclined square prism was examined using wind tunnel tests numerical simulations with aspect ratio of 6.25:1. The Synchronous Multi-Pressure Sensing System (SMPSS) technique used evaluate the characteristics structure, including surface pressure distribution, local force spectra, coefficient, coherence, Strouhal number. Moreover, Large-eddies simulation (LES) were also deployed investigate flow field morphology around structure. Results show that orientation, direction, angle inclination direction significantly affect prism’s characteristics. Several phenomena revealed. Forward enhances downwash flow, whereas backward counterpart upwash transverse produces noticeable modification vortex near base. These findings can inform structural design contaminant dispersion efforts.
