CFD-based analysis of Rusfors dam before and after rebuilding (English)
Abstract [en]

Hydraulic model studies of the Rusfors dam were previously made, the purpose of which was to examine the rebuilding solution for safe discharge of its design flood. In this work, two-phases computational fluid dynamics simulations were conducted to provide essential insights that help better comprehend the model test results. The hydraulic characteristics investigated in numerical modelling included the velocity profile, flow pattern profile and energy dissipation capacity.

Through analysis of the results obtained from numerical modelling and hydraulic model tests, the modified dam was found to have better energy dissipation capacity and sediment cleaning ability than the previous dam.

Abstract [sv]

Hydrauliska modellstudier av Rusfors dammen tidigare gjort, vars syfte var att undersöka återuppbyggnaden lösning för säker urladdning av dess utformning översvämning. I detta arbete har två faser computational vätska dynamik simuleringar genomförts för att ge viktiga insikter som hjälper bättre begripa de modelltestresultaten. De aspekter som undersöks i numerisk modellering inkluderar hastighetsprofilen , strömningsmönstret profil och energiförbrukningskapacitet.

Genom analys av resultaten från numerisk modellering och hydrauliska modellförsök, var den modifierade dammen visade sig ha bättre energiförbrukningskapacitet och sediment rengöringsförmåga än tidigare dammen.
