  2. 6. Experimental and analytical study of thermal mixing at reactor conditions

    Author : Mattia Bergagio; Henryk Anglart; Horst-Michael Prasser; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-cycle thermal fatigue; Hilbert-Huang transform; large eddy; WALE; rainflow; inverse heat conduction; adjoint conjugate gradient; Energy Technology; Energiteknik; Fysik; Physics;

    Abstract : High-cycle thermal fatigue due to turbulent mixing of streams at distinct temperatures is an interdisciplinary issue affecting safety and life extension of existing reactors together with the design of new reactors. It is challenging to model damage and thermal loads arising from the above mixing. READ MORE

  4. 7. On drops and turbulence in nuclear fuel assemblies of Boiling Water Reactors

    Author : Diana Caraghiaur; Henryk Anglart; Michele Andreani; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The study aims to develop the understanding of the mechanistic-type approach to quantify drop deposition in nuclear fuel assemblies of Boiling Water Reactors. This includes the effect of spacers. READ MORE

  5. 8. Experimental Study and Modelling of Spacer Grid Influence on Flow in Nuclear Fuel Assemblies

    Author : Diana Caraghiaur Garrido; Henryk Anglart; Dominique Bestion; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spacer grid influence; annular flow; deposition; Lagrangian Particle Tracking;

    Abstract : The work is focused on experimental study and modelling of spacer grid influence on single- and two-phase flow. In the experimental study a mock-up of a realistic fuel bundle with five spacer grids of thin plate spring construction was investigated. A special pressure measuring technique was used to measure pressure distribution inside the spacer. READ MORE

  6. 9. Mechanistic Modeling of Annular Flows at Near-Dryout Conditions

    Author : Wenyuan Fan; Henryk Anglart; Martin Rohde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kärnenergiteknik; Nuclear Engineering;

    Abstract : This work aims at advancing the modeling methodology for near-dryout annular flows using two different computational fluid dynamics (CFD) approaches. One is termed as the transported film approach, where the film flow is separately modeled by a simplified liquid film model and then coupled with the gas core simulation using various closures.
