Forces exerted by surface waves on piles
WebThis study utilizes three-dimensional simulations to investigate scour in combined wave–current flows around rectangular piles with various aspect ratios. The simulation model solves the Reynolds-averaged Navier–Stokes (RANS) equations using the k–ω turbulence model, and couples the Exner equation to … WebForce Exerted by Surface Waves on Piles. The Morison's equation allows us to calculate the force acting on piles only by unbroken surface waves, considering that at the …
