  1. 6. Design of cooling-air permeable coil support

    University essay from KTH/Hållfasthetslära

    Author : Rozbeh Ghassemi; [2023]
    Keywords : Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

    Abstract : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. READ MORE

  3. 7. CFD investigation of a unit cell inside a Plate Heat Exchanger

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  4. 8. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

  5. 9. Study on Lithium Battery Thermal Analysis For E-bike

    University essay from Högskolan i Halmstad

    Author : Sreekuttan Vijayan; Jais Jaimon; [2023]
    Keywords : Lithium-ion battery; e-bike; thermal analysis; forced convection cooling; natural air convection; temperature distribution; outlet ports; computational fluid dynamics;

    Abstract : E-bikes, often known as electric bicycles, are becoming more and more well-liked as green modes of mobility. High-capacity lithium-ion (Li-ion) batteries are utilised to power these e-bikes because of their extended cycle life, high energy density, and low self-discharge rate. READ MORE

  6. 10. Comparative Analysis of Modern Energy Systems for Ice Rinks

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

    Author : Pendar Hemati; [2023]
    Keywords : Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    Abstract : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. READ MORE
