Numerical Investigation of Flow in Porous Media Around a Mono-Pile under Steady Current
The study numerically investigates the three-dimensional (3D) flow features around a mono-pile with scour protection under steady flow condition. A hydrodynamic model based on Volume-averaged Reynolds-averaged Navier-Stokes (VARANS) equations with the Volume-averaged k-ω turbulence closure is develo...

The study numerically investigates the three-dimensional (3D) flow features around a mono-pile with scour protection under steady flow condition.
