  1. 26. Model Predictive Control for Ground Source Heat Pumps : Reducing cost while maintaining comfort

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Isak Bokne; Charlie Elf; [2023]
    Nyckelord :MPC; Model Predictive Control; heat pump control; electricity spot price; weather prediction; reducing cost;

    Sammanfattning : Today, the control of heat pumps aims to first and foremost maintain a comfortable indoor temperature. This is primarily done by deciding input power based on outside temperature. The cost of electricity, which can be rather volatile, is not taken into account. LÄS MER

  3. 27. Reliability Assessment of Passive ICS in an SMR as part of the PSA Analysis

    Master-uppsats, KTH/Fysik

    Författare :Graeme Trundle; [2023]
    Nyckelord :Passive system reliability; Probabilistic safety assessment; Reliability Methods of Passive Systems; Natural circulation; TRACE; RiskSpectrum; Passiv systemtillförlitlighet; Probabilistisk säkerhetsbedömning; Reliability Methods of Passive Systems; Naturlig cirkulation; TRACE; RiskSpectrum;

    Sammanfattning : Passive safety systems are increasingly being utilized in prospective nuclear power plant designs. Indeed, the use of safety systems driven by natural phenomena might be seen as an unmitigated virtue. LÄS MER

  4. 28. Assessment of the integration of solar heat power into food drying processes

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Charalampos Psilopoulos; [2023]
    Nyckelord :Sustainable; sustainability; co2 reduction; feasibility; solar thermal; direct steam generation; drying; food industry; scope 1 emissions; sdg; sustainable development goals; spray drying; drum drying; powder; food; Technology and Engineering;

    Sammanfattning : The long-lasting usage of fossil fuels has brought its negative impact on the planet and thus the society is turning towards more environmentally sustainable solutions in every aspect of life. This master’s thesis discusses the novel topic of integrating concentrated solar thermal collectors, which directly produce steam, to drying processes in the food industry, which is proven to currently emit significant amounts of Greenhouse Gases (GHGs).

  5. 29. CFD investigation of a unit cell inside a Plate Heat Exchanger

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Mattias Ly; [2023]
    Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

  7. 30. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andrea Martinez Sanz; [2023]
    Nyckelord :Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

    Sammanfattning : Testing of hardware to be used in space sometimes involves using vacuum chambers. The need to test hollow cathodes, used as neutralizers for some Electric Propulsion Thrusters, and low power Hall Effect Thrusters at OHB Sweden requires a vacuum chamber to be upgraded. LÄS MER
