Hydrodynamic forces on a pipeline with uneven embedment on either side, subject to oscillatory flow, are investigated numerically. Two-dimensional Reynolds-Averaged Navier-Stokes equations with a k-w turbulent model are solved to simulate the flow in the fluid. It is assumed the seepage flow in the...
