2. 1. Robust Numerical Wall Functions Implemented in OpenFOAM

   Author : Jon-Anders Bäckar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impinging jet; numerical wall function; Computational Fluid Dynamics; speed-up; OpenFOAM;

   Abstract : This thesis presents two new numerical wall models for computing Reynolds-Averaged-Navier-Stokes (RANS) equations with low-Reynolds-number turbulence models. Theobjective is to considerably reduce the total central processing unit (CPU) cost of thenumerical simulations of wall bounded flows while maintaining the accuracy of anylow-Reynolds-number turbulence model.

4. 2. Mechanistic Modeling of Wall-Fluid Thermal Interactions for Innovative Nuclear Systems

   Author : Roman Thiele; Henryk Anglart; Xu Cheng; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GEN-IV reactors; Wall heat transfer; Computational Fluid Dynamics; Wall functions; Reactor design; Supercritical water; Liquid metal; Energy Technology; Energiteknik; Fysik; Physics;

   Abstract : Next generation nuclear power plants (GEN-IV) will be capable of not only producing energy in a reliable, safe and sustainable way, but they will also be capable of reducing the amount of nuclear waste, which has been accumulated over the lifetime of current-generation nuclear power plants, through transmutation. Due to the use of new and different coolants, existing computational tools need to be tested, further developed and improved in order to thermal-hydraulically design these power plants. READ MORE
