Modellversuch und Numerik - Gegner oder Partner? (Numerics and scale model tests - opponents or partners?)
MetadataShow full item record
Scale model tests and numerical simulations are the two mainly used methods in hydraulic engineering. The paper describes both modelling techniques, typical scopes of application and as well basic information of costs and required time for the investigations. The positive effects of coupling both methods are exemplarily shown with the example of quantifying the local hydraulic loss of a built-in component in a pipe.
