Hybrid model of the lock filling/emptying system

Popis výsledku v původním jazyce

The paper describes the hybrid modelling of the design of the lock filling and emptying (F/E) system. It is a method of hybrid modelling, which combines physical and numerical modelling methods of flow. Hybrid modelling is mainly used to solve the hydraulic flow of a water complex in hydraulic structures. Optimizing and rebuilding the physical model is laborious and does not show all the results. The use of a numerical model allows to optimize only a part of the structure with using measurements on a physical model. The main advantages of hybrid modelling are the high reliability of results and the possibility of interpreting results that are not visible on the physical model. Within the project preparation of the Děčín lock, extensive research was carried out on the physical model of the lock. The aim of the research was to optimize the F/E system of the lock of long culverts. Based on the measurements on the physical model, an optimization of the filling system was necessary. Subsequently, the F/E system was optimized to reduce hydraulic losses using a CFD model. The optimized F/E system is up to 12% more efficient than the project preparation design. The hybrid modelling method can be used to increase the capacity of existing historic locks on the Elbe-Vltava Waterway (Czech Republic) without impacting the architectural character of the locks. The research was conducted as part of project no. DG18P02OVV004 entitled “Documentation and presentation of technical cultural heritage along the Elbe-Vltava Waterway” within a support programme for applied research and experimental development of national and cultural identity, funded by the Ministry of Culture of the Czech Republic.
