Abstract :
*(250~1000 words)
When designing navigation locks, several parameters must be taken into account: Apart from the construction and operation cost also the operation speed and safety must be considered. Tradi-tionally different kinds of models are used to determine the speed and safety of operation: For the pre-design phase often simple analytical approaches are used, while in later design phases more sophisticated one- or three-dimensional numerical models or physical models are used independently or in a hybrid modelling approach. With these models the flow rates, the development of the water levels and the resulting forces on the ship can be computed or measured. While the application of three-dimensional numerical models for the lock filling process was in the past limited to very few and extraordinary projects, nowadays their application becomes more and more engineering practise. In the design of locks it is very helpful to evaluate specific features of the flow with these models. But one must be aware that considering all aspects of the lock filling process offers several pitfalls which might be unexpected, particularly for unexperienced modellers. This is especially problematic if the modeller is already familiar with numerical modelling concepts in general (e.g. from finite element analysis of structures) and tries to transfer this knowledge to the process of lock filling: Unfortunately it is possible with the available numerical modelling packages to produce valid looking results for the lock filling simulations even if the physical meaning is limited or if the results are simply wrong. In this situation it would be more helpful if the modeller would have in-depth knowledge of the expected behaviour of the flow and the ship in the chamber, in order to judge the quality of the numerical results. In this presentation, we will show several aspects of the state-of-the art of numerical modelling of the lock filling process. We will introduce and give advise on the usage of different model classes. Furthermore, we will give a short outlook on the process of setting up a full three-dimensional numerical model for the lock filling process of a complex lock with water saving basins. As a quality assessment, we will present how the results should be validated with physical model results for the same experiment.
