| Abstract |
For this master’s thesis, a MATLAB code is developped for modelling lock filling and emptying. The 1D SWE are applied to model the water movement, and both the flexible and the rigid ship method are implemented to model the presence of a moored vessel. For the solution of the applicable system of (partial) differential equations, two numerical solution methods are implemented.After debugging the developped code, the obtained results are studied for the Denderbelle test case, for a lock chamber without a moored vessel. The sensitivity of the results to the numerical parameters for both numerical solution methods is studied, in order to select adequate values for these numerical parameters. For the selected numerical parameters, the results obtained with both solution methods are compared. Finally, one possibility to increase the applicability of this one-dimensional model is studied, namely including representative profiles for the momentum correction coefficient β, in order to better represent the concentrated filling jet. |
