Abstract

Turbulent patches occurring in environmental flows can arise from breaking internal waves generated topographically. The convective overturning of waves leads to shear instability and then to turbulence which develops into the fully mixed region in the place of initial wave breaking. The objective of the present studies is to explore the steady internal wave breaking observed in stably stratified flows past obstacles [1]. We use a numerical approach based on well-resolved Navier–Stokes DNS/LES methods using parallel multi-block architecture [2] with the Boussinesq approximation and sponge layer treatment to avoid wave reflection from upstream/downstream boundaries.
