  1. 11. BWR Reactor Fuel Channel Manufacturing Simulations

    University essay from KTH/Hållfasthetslära

    Author : Kalle Norell; [2022]
    Keywords : Bending; Boiling water reactor; Fuel channel; FEM; Bockning; Kokvattenreaktor; Höljerör; FEM;

    Abstract : Fuel channels are used to keep the components of a nuclear fuel bundle in place. The fuel channel of a new nuclear fuel which is being developed at Westinghouse has a complex geometry which creates challenges in the manufacturing process. FE simulations were developed of a two-stage forming process of the fuel channel. READ MORE

  3. 12. Effects of Immiscible Compressor Oil in a Flooded PSHE Evaporator : A Visual Study Approach

    University essay from KTH/Energiteknik

    Author : Joel Blomfelt; [2022]
    Keywords : ;

    Abstract : This paper deals with heat transfer in plate evaporators, with a focus on the effects caused by carried-over compressor oil ending up in the heat exchanger. A common standpoint in literature regarding the effect of immiscible oil contamination, in for example an ammonia PHE evaporator, is that the oil can accumulate as a layer on the plate surface causing an additional thermal conduction resistance.

  4. 13. Improving the understanding of heat transfer when boiling solid foods

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Dat Nguyen Trong; [2022]
    Keywords : fluid-to-particle heat transfer coefficient; heat transfer; pool boiling; boiling; simmering; starch gelatinization; unsteady-state heat transfer analysis; food engineering; Agriculture and Food Sciences;

    Abstract : Determination of the fluid-to-particle heat transfer coefficient hfp is a fundamental problem in food engineering. Solutions to this problem help food technologists and cooks prepare foods with desired characteristics more efficiently in time and energy use. This study aims to determine the hfp-value in simmering and boiling solid foods. READ MORE

  5. 14. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Melody Ghaderidosst; [2022]
    Keywords : Microarchitecture; TPMS; Gyroid; thermo-mechanical; computational homogenization; graphite; graphene;

    Abstract : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. READ MORE

  6. 15. Waste Heat Recovery with Organic Rankine Cycle Technology : A techno-economic analysis in vehicular applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Eric Ager; Victor Yllmark; [2022]
    Keywords : ;

    Abstract : Då den globala uppvärmningen ökar behöver vi hitta fler sätt att minska våra utsläpp av växthusgaser, särskilt inom transportsektorn som står för cirka 12 % av världens totala växthusgasutsläpp. Ett sätt att minska dessa utsläpp är genom att förbättra bränsleeffektiviteten på tunga lastbilar.
