  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. Reduced stress method for steel in class 4 cross-sections : Evaluation of the reduced stress method for a railway bridge

    University essay from KTH/Byggteknik och design

    Author : Therese Badrous; Ebba Lund; [2021]
    Keywords : FEM; Reduced stress method; Effective cross-section method; Local buckling; Steel cross-section; Class 4 cross-section; Railway bridge; FEM; Reducerad spänningsmetoden; Effektivt tvärsnittsmetoden; Lokal buckling; Ståltvärsnitt; Tvärsnittklass 4; Järnvägsbro;

    Abstract : The effective cross-section method, also called reduced cross-section method is generally used for steel in class 4 cross-sections in considering local buckling. This method is a bit complicated and time consuming, which often leads to engineers not using profiles in class 4 cross-sections. READ MORE

  4. 3. Aspects of gating system improvement in a cast iron foundry

    University essay from KTH/Materialvetenskap

    Author : Fahami Annan Green; Felix Göttfert; [2021]
    Keywords : Gating system; Cast iron; Foundry; Pouring basin; Offset step basin; Sprue; Ingjutssystem; Gjutjärn; Gjuteri; Gjutskål; Förskjuten steggjutskål; Nedlopp;

    Abstract : The gating system transfers the iron melt from the ladle to the void in the casting mould. The gating systems dimensions and designs are crucial for the success of a casting and a poor gating system is a leading cause of scraps. READ MORE

  5. 4. Subject-specific image analysis and computational modelling of the human Achilles tendon

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Johanna Panzar; Erika Thörn; [2021]
    Keywords : image analysis; Achilles tendon; FE model; biomechanics; CT image; Technology and Engineering;

    Abstract : Achilles tendon rupture is becoming more prevalent with an increasing population of middle aged people participating in recreational sports. A torn Achilles tendon will likely not regain its original function, and it is unknown what treatment options are optimal. READ MORE

  6. 5. Wave Energy Concept Benchmarking

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Petter Larsson; Gustaf Rudbeck; [2021]
    Keywords : Budal K; Linear waves; Oscillating water column; Point absorber; Wave energy; Budal K; Linjära vågor; Oscillating water column; Point absorber; Vågenergi;

    Abstract : Denna rapport ämnar undersöka de vanligast förekommande typerna av teknologier för vågkraftverk (eng. Wave Energy Converter, WEC) teknologier för att jämföra de olika konceptens förmåga att absorbera vågenergi. Koncept som undersöks är punktabsorbatorer och oscillerande vattenkolumner. READ MORE
