2. 1. Experimental analysis of thermal mixing at reactor conditions

   Author : Mattia Bergagio; Henryk Anglart; Paolo Vinai; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing estimator; empirical mode decomposition; Hilbert-Huang transform; uncertainty assessment; radial heat flux; Energy Technology; Energiteknik; Fysik; Physics;

   Abstract : High-cycle thermal fatigue arising from turbulent mixing of non-isothermal flows is a key issue associated with the life management and extension of nuclear power plants. The induced thermal loads and damage are not fully understood yet. READ MORE

4. 2. 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
