Numerical study on evolution of an internal solitary wave across an idealized shelf with different front slopes

⿢Numerical simulations are performed to investigate the flow evolution of an internal solitary wave of depression over an idealized shelf with different front slopes.⿢A finite volume method is used to solve the Reynolds averaged Navier-Stokes equations using a k-ε model for the turbulent closure.⿢Physical components in the turbulent energy budget throughout wave evolution are differentiated during the wave-obstacle interaction.⿢Effect of three physical parameters that influence wave evolution is examined, which are front slope, depth ratio and incident wave amplitude.
