Abstract

Water jets are widely used in seabed scouring and desilting applications. In the present work, dedicated tests have been conducted using a jet scour model test platform and sand beds containing grains with different sizes. The FLOW-3D simulation software has also been used to tackle the problem form a numerical point of view. The boundary conditions of the simulation have been optimized to reduce the gap between the numerical results and the outcomes of the experimental tests. Scour area calculation has been based on a RNG k-ε Turbulence model. Moreover, the FAVOR (Fractional Area Volume Obstacle Representation) technology has been selected for grid division to make the simulation results more accurate. Jet scours with inclination angles of 10–20° have been simulated. It has been found that jet scouring is greatly affected by the environmental water flow, that is, water flow can weaken the scouring capacity of the jets.
