1. 1. Experimental Study of Post-Dryout Heat Transferin Annuli with Flow Obstacles

   Författare :Ionut Gheorghe Anghel; Henryk Anglart; Michele Andreani; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; annulus; post-dryout; temperature distribution; flow obstacles; new measurements; SRA - Energy; SRA - Energi;

   Sammanfattning : An experimental study on post dryout heat transfer regime in annuli with flow obstacles was conducted in the High-pressure Water Test (HWAT) loop at the Royal Institute of Technology in Stockholm, Sweden. An annulus consisting of two concentric heated pipes (12.7x24.3) mm, with total heated length equal to 3650 mm was employed as a test section. LÄS MER

3. 2. On drops and turbulence in nuclear fuel assemblies of Boiling Water Reactors

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

   Sammanfattning : 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. LÄS MER

4. 3. Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water

   Författare :Hua Li; Pavel Kudinov; Michele Andreani; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermal Stratification; Mixing; Pressure Suppression Pool; Containment; Thermal Hydraulic; GOTHIC; Light Water Reactor; Fysik; Physics;

   Sammanfattning : Steam venting and condensation in a large pool of water creates both a source of heat and a source of momentum. Complex interplay between these two sources leads to either thermal stratification or mixing. LÄS MER
