Effect Of The Earth’S Rotation On Hydraulic Jumps

—The influence of Earth’s rotation on the structure and mixing of internal hydraulic jumps is studied by means of three-dimensional numerical simulations with varying values of the Coriolis parameter. The Navier-Stokes equations with vertical density stratification are solved numerically for an incompressible fluid. The flow structure varies across the width of the channel due to rotation. In particular, different jump structures are observed at positions across the width of the channel. Mixing also changes as a result of rotation, with larger mixing values occurring at lower rotation rates and on the left side of the channel (when looking in the direction of flow).
