Abstract: Abstract:The propagation and dissipation of internal waves over continental shelf bathymetry are complex phenomenon. The waveform would regenerated while transmitting a submerged deep-shallow-deep topography. To study the effect of the marine topography on the evolution of an internal wave, numerical simulation is utilized to perform the flow evolution and waveform inversion of a large depression internal over a trapezoidal obstacle with different plateau. A finite volume based Cartesian grid method is adopted to solve the Reynolds averaged Navier-Stokes equations using a k-ε model for the turbulent closure and porous media model. Numerical results reveal that the regenerated waveform does not occur due to baroclinic wave. The shorter plateau length would induce strong vortex in back of the obstacle and cause the significant dissipation of wave amplitude, vorticity and turbulent kinetic energy. However, the level of the phenomenon decrease as the plateau length is larger than the wavelength. Index Terms—Internal solitary wave; RANS equation; k-ε turbulent model; Flow field.
