  1. 1. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Laszlo Zorc; [2023-08-18]
    Keywords : ;

    Abstract : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. READ MORE

  2. 2. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yujun Han; [2023]
    Keywords : Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Abstract : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. READ MORE

  3. 3. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Kreshnik Margaritari; [2023]
    Keywords : Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Abstract : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  4. 4. Thermal and flow field validation of lattice Boltzmann method solver

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : André Skagius-Kallin; [2023]
    Keywords : Lattice Boltzmann method; heat transfer; flow field;

    Abstract : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. READ MORE

  5. 5. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

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

    Author : Jennifer Ly; [2023]
    Keywords : Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

    Abstract : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.
