  1. 1. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oskar Sundberg; [2023]
    Keywords : geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Abstract : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. READ MORE

  3. 2. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    University essay from Lunds universitet/Materialteknik

    Author : Johan Ranstad; [2023]
    Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE

  4. 3. Normalization of Cooling Demand in Buildings, development, and evaluation of methods

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

    Author : Xingtong Wu; [2022]
    Keywords : ;

    Abstract : Because of the increasing demand for indoor thermal comfort and the better insulation performance of building envelopes, cooling demand is an increasingly important part of building energy consumption despite the cold climate in Stockholm. Finding a way to normalize cooling demand to climatic conditions will help better energy audits to improve the building performance to achieve energy-saving. READ MORE

  5. 4. Modelling an air handling unit, building and occupant, regarding energy, moisture and frost protection

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Marius Daugela; [2022]
    Keywords : Technology and Engineering;

    Abstract : Frost formation in heat exchangers is an often accruing issue in cold climates. The aim of the project is to calculate the risk of frost formation in different Swedish cities by modeling vapor and frost behavior in heat exchangers... READ MORE

  6. 5. A Method of CFD-based System Identification for Standardized Co-Simulation

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Olle Lindqvist; [2022]
    Keywords : CFD; system identification; FMI; SSP; co-simulation; steady-state;

    Abstract : System simulations are a useful tool when analyzing complex systems. For example, simulations can be cheaper than physical testing of the actual system. Models canalso be created for systems that do not exist yet, that would be impossible to analyze experimentally. READ MORE
