This study investigates the flow characteristics around complex bridge piers in both single and tandem configurations, aiming to enhance understanding of their hydrodynamic performance. The research gap identified is the limited exploration of flow dynamics specific to bridge pier configurations, particularly under real-life flow conditions. The objectives of this study were to analyze the velocity, pressure, and vortex distributions around the piers, as well as to evaluate the drag coefficients for different configurations. Using Computational Fluid Dynamics (CFD), time-averaged, normalized mean stream wise and cross-stream velocities, pressure distributions, and y-vorticity values were examined. The key findings include the highest velocity values at the pile sections, significant pressure effects on the front face of the piers, and the formation of prominent vortices near the pile cap. Additionally, drag coefficients were found to be 1.090 for the single pier and 1.102 for the tandem pier, highlighting the significant impact of pier configuration on hydrodynamic performance. This study provides valuable insights into the fluid–structure interactions around bridge piers, contributing to the design optimization and safety analysis of bridge structures in complex flow conditions.
