  1. 1. 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. 2. A pre-study for functional coatings evaluated on light metals to be applied on a new HPDC Mg-alloy : Investigating tribological and thermophysical properties, as-cast and coated

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Louise Albo Zieme; Pontus Bergstedt; [2021]
    Keywords : reciprocating dry sliding wear test; thermophysical test; NiP-SiC; Ni-SiC; functional coatings; progressive scratch test; adhesion; magnesium alloy; aluminium alloy; hardness.;

    Abstract : Magnesium with two-thirds of the density compared to aluminium and one-quarter of steel, intrigues product developers and material scientists due to the light metal’s excellent combination of strength to weight ratio as well as their capability of being produced as a High Pressure Die Cast component compared to other ferrous or light metal alloys.   However, a magnesium alloy inherits some concerning drawbacks, limiting the exploitation in structural applications and mechanical design such as automotive, heavy machinery and aerospace components.

  4. 3. Development of an interatomic potential for the study of the thermodynamic properties of oxide coumpounds containing americium

    University essay from KTH/Fysik

    Author : Simon Orlat; [2021]
    Keywords : ;

    Abstract : For the purpose of americium recycling, the effect of americium content on the nuclear fuel behaviour needs to be investigated. Atomic scale simulations and classical molecular dynamic simulations provide a tool of choice for the study of thermophysical properties of the nuclear fuel. READ MORE

  5. 4. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

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

    Author : Brianna Kilberg; [2020]
    Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

  6. 5. Thermal Acoustic Flow inside an Ultrasound Resonator

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Enrico Corato; [2020]
    Keywords : Microfluidics; Ultrasound; Acoustofluidics; Thermal gradient; Thermoacoustic; Technology and Engineering;

    Abstract : This thesis aims at investigating the interaction between thermal gradients and acoustic fields in microfluidic devices. In the research branch of Acoustofluidics, which bridges together acoustics and fluid dynamics, inhomogeneity in the medium has gained great interest due to the novel physics behind and the potential in manipulating submicrometer particles.
