Abstract

A numerical investigation of the aerodynamic characteristics of a streamlined box girder was conducted based on computational fluid dynamics (CFD). The SST k–ω turbulence model was employed to simulate the flow field around the girder. The time histories of the three-component aerodynamic forces, the distribution of mean surface pressure, as well as the pressure and velocity contours of the flow field were systematically analyzed. The results reveal the flow behavior of the incoming air as it passes over the girder surface and elucidate the intrinsic relationship between flow characteristics and wind pressure distribution. The study provides a clearer understanding of the aerodynamic mechanisms governing the wind-resistant performance of streamlined box girders and offers a valuable reference for their aerodynamic design and optimization.
