The placement of artificial reefs (ARs) significantly influences local hydrodynamics and nutrient transport, both which are crucial for enhancing marine ecosystems improving habitats. Large eddy simulations (LESs) performed to study the flow field around a cuboid reef (CAR) with three inflow angles (α = 0°, 45°, 90°). numerical method is successfully validated experimental data, reasonable grid resolution chosen. results demonstrate that case an angle 45° exhibits superior performance, including largest recirculation bubble length maximum volumes upwelling wake regions. Stronger turbulence also observed CAR at this angle, attributed intensified shear layer. instantaneous features torn horseshoe vortices rollers shed from layer, further develop into hairpin vortices.
