  1. 1. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Olivia Johansson; [2023]
    Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

    Abstract : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. READ MORE

  3. 2. Comparison and optimization of extracellular vesicle (EV) capturing on functional thin films for their molecular profiling

    University essay from KTH/Tillämpad fysik

    Author : Prattakorn Metem; [2023]
    Keywords : extracellular vesicle; plasmonic nanohole array; atomic force microscopy; fluorescence analysis; extracellulära vesiklar; nanohålsuppsättning; atomkraftsmikroskopi; fluorescensanalys;

    Abstract : Extracellular vesicles (EVs) are lipid bilayer encapsulated nanoparticles which have emerged as an excellent source of biomarkers for multiple diseases, including cancer. However, they are highly heterogeneous in their molecular compositions which remains a major challenge hindering the utilization of their biomarker potential. READ MORE

  4. 3. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Linnéa Tebelius; [2022]
    Keywords : Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Abstract : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.

  6. 5. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers

    University essay from Luleå tekniska universitet/Signaler och system

    Author : Caroline Holmström; [2020]
    Keywords : ;

    Abstract : Loudspeakers transform electrical energy into acoustic waves but most of the electrical energy is lost as heat. It is possible to increase the electro-acoustic efficiency by changing the electrical, mechanical or acoustical design of the loudspeaker but with these changes come unwanted side effects. READ MORE
