| Abstract |
In this report, a one dimensional, vertical (1DV) hydrodynamic model is presented which describes the turbulent boundary layer flow over plane and hydraulically rough beds under the influence of combined (colinear) oscillatory and current flows in the freestream above the boundary layer.
The numerical approach to solve the governing equations and boundary conditions is carefully described, including some turbulence modelling aspects related to the mixing-length model and the model. e-kBased on the described hydrodynamic model and numerical approach, a computer code is developed, which allows to study several aspects of (interacting) wave and current boundary layers without excessive computational costs.
Some testcases are presented, in order to provide a first testing of the code through comparison of the numerical predictions with published experimental and/or numerical data. The agreement between the results and the published data is satisfactory. Other testcases are merely presented to give an overview of the capabilities of the code.
Prospects for future research with the developed 1DV model and computer code are indicated. |
