Description
Weiqun Liang and colleagues simulate water flow around tandem bridge piers using three-dimensional large eddy simulation. Their 2025 study examines how wakes from multiple piers interfere with downstream flow and threaten structural safety.
Eight equally spaced piers were modelled across varied flow velocities, spacing ratios, and pier counts. Upstream piers showed the highest pressure, decreasing downstream, while downstream pressure peaks shifted sideways. Vortex structures evolved from intense small scales toward weaker diffusion as flow passed. Lift fluctuated periodically, and some piers experienced negative drag. More piers improved flow stability overall, while wider spacing reduced interference. Shedding frequencies and resonance patterns changed with every parameter tested.
