  2. 11. CFD and data-driven modeling for safe spillway discharge

    Author : Shicheng Li; Anders Ansell; James Yang; Robert Boes; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discharge safety; hydraulic design; spillway; discharge capacity; aerator; two-phase flow; air entrainment; energy dissipation; CFD; data-driven modeling; Betongbyggnad; Concrete Structures;

    Abstract : A spillway is a crucial dam structure that regulates water levels and prevents the dam from overtopping. The majority of the dams in the world were constructed before the 1980s. Compared to the current design flood standards, many spillways are undersized, e.g. READ MORE

  4. 12. Development of an Improved Thermal-Hydraulic Modeling of the Jules Horowitz Reactor

    Author : Reijo Pegonen; Henryk Anglart; Yann Bartosiewicz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jules Horowitz Reactor; CATHARE2; STAR-CCM ; FLICA4; Material Testing Reactor; Computational Fluid Dynamics; System code; Reactor modeling;

    Abstract : The newest European high performance material testing reactor, the Jules Horowitz Reactor, is under construction at CEA Cadarache research center in France. The reactor will support existing and future nuclear reactor technologies, with the first criticality expected at the end of this decade. READ MORE

  5. 13. Modeling of planing craft in waves

    Author : Karl Garme; Dan Zenkert; Richard Akers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; marine; ocean; Planing craft; time-domain simulation; design loads; Vattenteknik; Water engineering; Vattenteknik;

    Abstract : Simulation of the planing hull in waves has been addressed during the last 25 years and basically been approached by strip methods. This work follows that tradition and describes a time-domain strip model for simulation of the planing hull in waves. The actual fluid mechanical problem is simplified through the strip approach.

    Abstract : Hydraulic turbomachines have played a prominent role in the procurement of renewableenergy for more than a century. Embedded in the context of general technological progress,their design for efficiency and reliability has reached an outstanding level of quality. READ MORE

  7. 15. Safety, Security, and Semantic Aspects of Equation-Based Object-Oriented Languages and Environments

    Author : David Broman; Peter Fritzson; Henrik Nilsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modeling; Simulation; Equation-Based; Object-Oriented; Modelica; Type System; Semantics; Language Safety; Secure Simulation; Computer science; Datavetenskap;

    Abstract : During the last two decades, the interest for computer aided modeling and simulation of complex physical systems has witnessed a significant growth. The recent possibility to create acausal models, using components from different domains (e.g., electrical, mechanical, and hydraulic) enables new opportunities. READ MORE
