A Numerical Simulation of a Tidal Bore Flow
A numerical model was developed based on the Cubic-Interpolated Pseudo-particle (CIP) Combined Unified Procedure (CIP-CUP or C-CUP) method equipped with a Large Eddy Simulation (LES) model and a re-initialization method. The model was validated and applied to the tidal bore flow with a weak breaking front. In the tidal bore flow, the model equipped with a LES turbulence model reproduced accurat...

Lubin), glock [email protected] (H. Chanson). A tidal bore is a natural and fragile phenomenon, which is of great importance for the ecology of an estuary. The bore development is closely linked with the tidal range and...
متن کاملThree-dimensional numerical simulation of the hydrodynamics generated by a weak breaking tidal bore
A tidal bore is a positive surge propagating upstream as the tidal flow turns to rising in river mouths exhibiting a converging funnelled channel forms during low freshwater conditions. While some recent laboratory experiments brought new insights to the turbulent motion generated by tidal bores, a numerical model based upon the Navier-Stokes equations is proposed to investigate the complicated...
متن کاملFlow Field in a Tidal Bore: a Physical Model
Abstract: A tidal bore may form in a converging channel with a funnel shape when the tidal range exceeds 6 to 9 m. The advancing surge has a major impact on the estuarine ecosystem. Physical modelling of an undular bore has been conducted based upon a quasisteady flow analogy. The experimental data highlight rapid flow re-distributions between successive wave troughs and crests as well as large...
