  1. 11. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

    University essay from KTH/Materialvetenskap

    Author : Felix Göttfert; [2023]
    Keywords : Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

    Abstract : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. READ MORE

  3. 12. Frame Sections for Highly Insulated Industrial Doors

    University essay from Lunds universitet/Innovation

    Author : Frida Sterner; Sofia Björnsson; [2022]
    Keywords : Product development; ASSA ABLOY; Frame section; Overhead sectional door; U-value; Technology and Engineering;

    Abstract : Detta examensarbete, utfört i samarbete med ASSA ABLOY Entrance Systems, syftar till att utveckla en ny ramsektion för industriella takskjutportar. Takskjutportarna är en del av den befintliga produktportföljen och finns i två olika tjocklekar, 42 och 82 mm. READ MORE

  4. 13. Thermal-hydraulic safety analysis of the HTTU and GEMINI+ cores in TRACE

    University essay from KTH/Fysik

    Author : Eva Joosten; [2022]
    Keywords : HTGR; TRACE; Thermal-Hydraulics; Safety; Heat Transfer; HTGR; TRACE; Termisk-Hydraulik; Säkerhet; Värmeöverföring;

    Abstract : With the coming of Generation IV systems, there is a need for thermal-hydraulic codes to model such advanced reactors. Codes for High Temperature Gas-cooled Reactors (HTGRs) already exist, but often suffer from insufficient validation and little user experience. READ MORE

  5. 14. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  6. 15. 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.
